Customer Ratings & Reviews

I ordered the Ultrahuman ring in raw titanium after selecting the size and color using the sizing kit. I went back and forth on finger placement and size and finally decided on the index finger of my left hand. Now that I have the actual ring, the finger choice was a good one, but a half size smaller would’ve been ideal if half sizes were available. The color is identical to the sample color. The “titanium” metal looks like it will last and not show scratches. However, to minimize scratches since I do a lot of yard work, I found a pack of 10 silicone protection covers in a variety of colors for less than $10. The ring is much larger than any cosmetic ring I would wear, but it doesn’t get in my way or interfere with anything. I only notice it when I turn a doorknob or make a sharp turn when driving. It comes off a little easier than the sample plastic ring did because of the difference in material. It does want to slip off when in water. Depending on the tightness of the fit, it might be a good idea to remove it before swimming. The app does have a “locate my ring” feature if the ring is lost, but it’s not very helpful. The phone had to be within 4 feet of the ring before it could detect it. At that point it told me the direction to go to find it. The charging and set up instructions were very easy to follow. Once fully charged, the lithium polymer battery should last 4-6 days. The ring should be charged at around the 30% mark and not drained. The charging level is monitored in the app. On day 3 I had 58% charge left so I should get 6 days between charges. Since I probably won’t remember to check the battery level every day, it would be nice if the ring would vibrate or something to let me know it’s time to charge it. The big question is how long the battery will last since that’s the life expectancy of the ring. When the duration of a full charge starts to decrease to 4 days, there are troubleshooting steps in the app to restore the interval to closer to 6 days. There is tons of data in the app and it will take me some time to go through it all and decide how to apply it. The app says it will take 15 days for it to calibrate and learn my habits. So far I’ve been able to monitor sleep duration, pulse, and steps. The app has notification reminders to get up and move, to stop caffeinated drinks close to bedtime and to go to bed earlier. Some days I agree with its interpretation of how well I slept and some days I don’t. On a night I thought I slept really well, the app gave me a score of 77 and said I got up several times during the night - which I didn’t. On a night when I was awake a lot, it gave me a score of 89 and said I slept well. When I got out of bed this morning it said I had walked 689 steps already. Maybe it’s still calibrating, but some of the data seems a little wacky. The price tag is a little high, but unlike some other fitness trackers, there is no subscription required with the Ultrahuman ring. When the subscription price is taken into consideration, the price seems more reasonable. I did get an email about purchasing extended coverage for damage or theft. The 2 year plan for $54 will replace the ring one time if damaged, stolen, lost or if it needs to be resized due to weight loss. I’ve worn fitness trackers on my wrist before, and have always eventually given up on them. They were in the way and the face would get scratched. They were too uncomfortable to wear while sleeping. The advantage was being able to easily see my steps and the time of day. With the ring, all the feedback (and there is a lot of it) is in the app. A wish list for the ring itself would be a little window that shows the time of day and the charge level. It could even be on the inside. Other than that, I can’t see any improvements that are needed, except perhaps the accuracy, which is yet to be seen.

The Ultrahuman Air Ring is a great alternative for anyone who struggles to consistently wear a watch, or keep track of one (that’s me). The ring itself is extremely lightweight and virtually unnoticeable while wearing it. I’m usually sensitive to jewelry and don’t wear any, but I’ve had no issues with this ring so far. The Good - the ring has an impressively long battery life. I’ve been charging it every 2–3 days, but only because I happened to be near my charger and relaxing, not because it needed it. It tracks a wide range of metrics and seems very accurate, especially for sleep and heart rate. The data is incredibly detailed, sometimes almost too detailed. The app is visually stunning and fairly intuitive, though there is a slight learning curve that some users might find frustrating. The Bad - first off, the firmware. I ran into issues updating it, and a quick search showed I wasn’t the only one. It seems the problem has since been resolved, it left me a bit wary about future updates. Also, while the app is beautiful, interpreting the data can be a challenge. It sometimes feels like there’s too much information and not enough context, such as comparisons to others in my demographic (age, weight, gender). I’m very tech-savvy, but my wife isn’t, so I asked her to go through the app with me. When we explored the app together, she struggled to make sense of it, which makes me wonder if others might find the large amount of data more confusing than helpful. Another downside is the number of in-app “Power Plug” subscriptions. Some, like glucose monitoring, are significantly more expensive than the ring itself. I personally wouldn’t feel comfortable spending that kind of money while firmware issues are still fresh in my memory. That said, I did subscribe to the Cardio Power Plug and have been happy with it so far. On a side note: I had concerns about wearing a ring while playing guitar. Fortunately, I found a silicone cover for the ring that has made a world of difference. The cover prevents the ring from banging against my guitar or other surfaces, and has been key to me being able to wear it for days on end. Overall - This is a fantastic ring and a refreshing alternative to my smartwatch, which I use inconsistently. I love that the battery lasts several days, making it easy to track sleep without having to recharge it every night. It hasn’t caused any sensitivity issues, and so far, it seems the firmware bugs seem to be behind us. I’m excited to check out more of the free Power Plugs (like the Vitamin D tracker) and can’t wait to see what features they roll out next.

Summary: The Ultrahuman Ring AIR smart ring is a great option for tracking and helping improve your health. The Ring AIR is very light weight and almost undistinguishable from other fashionable rings if you want to be stealthy. It's a great way to get reminders throughout the day to get up and get active or know when your caffeine window is open or when to start winding down for the night. It's not the best activity tracker, (walking, running, weights, etc), but it doesn't claim to be. I happened to recently have a baby and wanting to make sure I'm a good parent, I neglected my sleep to care for the baby. The Ring AIR helped me track my sleep and understand how I'm resting throughout the day and night. It predicted my immune system might be compromised if I neglect my sleep. I tend to get sick when I don't get enough sleep, it was pretty much spot on. It was a great way for me to get reminders and nudges to make sure I'm also taking care of myself. I'd DEFINITELY recommend this for the person that's looking to keep better tracking of your sleep and general activity throughout the day. I DON'T recommend this for someone looking to track their exercise. In the Box: Ultrahuman Ring AIR smart ring Charging Dock USB-C cable Setup: The Ultrahuman Ring AIR was very easy to setup and the app makes it simple. The app guides you through the whole process. The only thing you need to be aware of is the Ring AIR needs to be charged before use.

Searching for a way to track key health measurements such as movement, heart rate, and sleep patterns without a smart watch is simple with the Ultrahuman RingAIR. You can keep your traditional watch and just slide on a small ring to get to tracking your stuff! UNBOXING - When you first open the box, you are immediately presented with the ring on its own. Nice presentation! After you remove the ring, pull out the first layer, and you can then remove the charging dock and the included braided USB-C charging cable. I was genuinely surprised by the braided charging cable as it added a premium touch. There is no AC adapter included, so you will have to use your own. Pairing the ring to your phone/Ultrahuman app was fairly simple. You are advised to charge the ring first for about 30 minutes prior to pairing it with the app. During the pairing process, the app checks for firmware updates and updates the ring as needed. Soon after, you're up and running. PERFORMANCE - The ring monitors various health metrics, including sleep stages, step count, heart rate, and skin temperature, as well as other important statistics related to these measurements. I found that the ring typically lasts a couple of days on a full charge, although I always make sure to recharge it before the battery gets too low. Usually, I place it on the charging dock in the morning after getting ready for my day. In the Ultrahuman app, you can configure the ring to optimize its performance and improve battery life by selecting from three modes: Turbo, Chill, and Critical. APP - The Ultrahuman app is both simple and frustrating to use. It prominently displays the measurements tracked by the ring and does an excellent job of presenting this data. However, the app contains many unnecessary features that make it feel clunky, and it often comes across as a sales pitch for other Ultrahuman products and services. One of the features that I have appreciated throughout the day, though, has been alerts on when to taper off caffeine intake to help me improve my sleep. CONCLUSION - Overall, I believe the Ultrahuman RingAIR is an excellent product and a compelling alternative to a smartwatch. While it has some drawbacks, it effectively fulfills its intended purpose. The material, raw titanium, not only looks great but also feels high-quality. My favorite feature has been the sleep tracking, which allows me to monitor my sleep quality and make necessary changes for a better night's rest. If a smartwatch is not your thing, but you want to monitor key measurements like heart rate, sleep tracking, movement, and skin temperature, then you shouldn't be disappointed with the RingAIR.

Seems like tracking biometric data is the new fitness and health trend… and I jumped all in. Several companies have tried the wearables market, but I’ve been really impressed by the Ultrahuman Air. Given it’s a wearable ring, the ring has to fit well and be comfortable enough to keep on consistently in order to maximize your benefits. The sizing process is super simple, you get sent a recyclable box with a sample ring that are clearly labeled in different sizes. There’s also a swatch that has examples of the ring colors. Once you receive your ring, use the QR code or search for the UltraHuman app, and the app will guide you step by step through pairing. After your ring is connected, just wear it consistently. Period. That’s it. I’ve kept my ring on during CrossFit workouts involving barbell work, kettle bells, and pull ups, and my ring survived. The bottom surface where the ring contacts the bars looks a little shinier and polished due to rubbing on the barbells, but otherwise can’t tell from a distance. The battery lasts several days, I start getting nervous when any device gets around 25% charge; so me personally I have been charging my ring after 4 days. The app tracks your sleep cycles, gives you your optimum caffeine intake window, plus the typical metrics like your heart rate, VO2, etc. there’s only one flattened portion on the inside where the sensors are, so you do need to make sure the ring is positioned correctly.

Before getting the ultrahuman ring, I was curious since I already have a smart watch with the health monitors and stuff, what could the ultrahuman do that was better. Would I not need my smartwatch anymore? Well, after more than a week of use, the verdict is that the Ultrahuman ring is a whole different and separate device to monitor my health. It does things my watch doesn't and vice versa. Each product has their own unique place. First off, the Ultrahuman sizing box is pretty nice and will give you a way to try on before buying. It also has samples of ring colors for you to choose from. My personal thought is that you can't go wrong with any of the colors, they all look great. And ultimately, although I wanted a device to monitor my health, I didn't want anything that stood out as such. It is also water resistant so you can shower or even just wash your hands with it on. Battery life is approximately 4 days which is nice and recharge time is approximately 90 minute, even though they say it lasts 4-6days. Where the Ultrahuman really shines is the in depth detail of your health that most watches doesn't do. If you are looking for something to give you more detail than just steps and heartbeat, the Ultrhuman is it. I can see this device helping me monitor my health between doctor visits.

Verdict: The Ultrahuman Ring Air is a great option for wearable data if you don’t have a smart watch that does that well (not all of them do) or if you like to wear traditional analog watches. It seems to be reliable enough at tracking the data that it advertises, it conducts interesting analysis of the data, and it aims to provide actionable insights for a better life. I was able to get six days of battery life on “Turbo” mode, leading me to think that I could get much longer on “Chill” mode (app estimates 10.4 days). Experience. I have been using a variety of GPS watches since the early 2000s and smart watches since the very first one. I have been increasingly interested to track as much body data as possible, and have mostly been disappointed with the primary smart watch I use (from the largest brand in the market). As a result, I bought a different smart watch (from an outdoors brand) to get better insight. I currently wear both to evaluate the consistency of collected data. Ultimately, I what I want is actionable or useful insights that can improve my life. The Ultrahuman Ring Air is my first non-watch wearable. First impressions. First, I really appreciate the availability of a sizing kit to better inform my choice of color / finish and size. Once I received the ring, I was most surprised about how light it was. I was expecting the ring to feel more like a metal ring, but it actually feels like the whole thing is plastic (the outer shell is in fact metal). The ring looks pretty nice; if worn on a ring finger, I think people would assume it’s just a wedding band (specially for men). I like the charger concept and wireless charging; it’s easy and fast to use. Performance. The ring appears to do a great job at capturing the data that it advertises: sleep, temperature, movement, heart rate, and women’s health (not tested). Battery life if quite good actually, with up to 10 days on chill mode. The Ring Air offers a way to track health data in the most discreet way and without a smart watch. When I run, I don’t bring my phone, so I was worried that the ring would not capture any data. I was wrong! When I finish my runs, the app is able to pull all data from the ring – this is great for my habits. Data. I have been interested to test the consistency of data across different devices. The Ring Air has been very consistent on skin temperature data, noticing abnormal temps every time I slept in a new location, and matching fairly closely with my watch that tracks skin temp (I trust the Ring Air more). I have noticed significant differences in movements at night; the ring reports only 6 (there is no way!), while my smart watch says 26 (I trust the watch here). My steps are off by 30% between the ring and the watch, with the Ring Air being lower by 20% than one watch, and lower by 10% than the other watch (not sure which is more accurate there). Sleep data is quite different from two apps with one smart watch, to the other smart watch, to the ring – I assess that the data from the Ring Air is good and close to the smart watch I trust. The sleep insights from the Sleep section of the Ring Air app is great – lots of great tips there. The Weekly digests are helpful and capture key takeaways for improvements. BOTTOM LINE: data across devices will be different. Pick one and develop good habits based on improving from the baseline provided by the device you choose. Durability. The outer shell is made from Titanium reinforced with Tungsten Carbide Carbon coating. After putting this ring through the ringer for 6 days, including yard work, weight lifting, doing dishes daily, 26 miles of running, etc., it still looks good. There are some small scratches here and there, but I expected much worse. It’s standing up to the abuse quite well so far. What I love: - Decent variety of finishes / colors - Better battery life than I expected (6 full days on turbo mode) - No subscription costs! Once you buy it, you have access to your data forever - Water resistant to 330m - Consistent data for sleep, HR, movement, and temperature to give actionable insights. Great weekly reports - Ability to put on airplane mode and still record your data - It also records data even if your phone is not with you - It has a “Find my Ring” feature, it’s not perfect but better than not having one at all. Of note, it would take a while to find the ring (10-20 sec delay on signal strength… but I think I would eventually find the ring) - I like the insights from “Brain Waste Clearance”. What I don’t love: - The ring should absolutely have some tactile markings where the sensor bump is so that you can quickly feel if it’s located on the palm side of the finger. Currently, it’s not really possible to tell the orientation of the ring when you are wearing it unless you wiggle it enough to see the interior of the ring. Tactile markings could just be a raised dot that is easy to feel, but not visible or uncomfortable. - I wish these came in half-sizes. My ring is a little too tight for my index and slightly too loose for my ring finger. I end up using the ring on both fingers: on the ring finger most days because it’s more comfortable and then on the index when my hands are going to be wet or sweaty so that I don’t l lose it (it would just slip off I think). - I’ve been wearing the ring for eight days now, but the Ultra Age hasn’t calculated yet (it says available after 7 days). - Cardio age fluctuation… Initially, my cardio age was 39, seven days ago. Now it’s 43. My cardio score from my smart watch has moved in the opposite direction in that time, going from 42 to 37. I have increased my cardio in the last few weeks and getting fitter, so the progression from my smart watch makes more sense than the one on the ring. - The Ultrahuman app doesn’t know when you are traveling to a different time zone. While traveling in Europe, the app was still telling me to start winding down and avoid sunlight to promote sleep when it was 7:30 am where we were in Europe. After 2.5 days, it finally caught up with the local time. Overall, I am happy with this ring, but I don’t think everyone will get the same utility across the board. If you already have a smart watch you love that does sleep tracking, HR, movement, and temperature, then don’t buy this… it will be redundant. Personally, I find that this ring complements my smart watch from a leading manufacturer, as it captures better data and gives me better insights. If I only used that smart watch, I would still buy this ring for a better health picture. However, the ring gives me similar data and analysis as my other smart watch (from an outdoor manufacturer). If you wear analog watches, then you should definitely buy the Ring Air because it will give you insights that may significantly improve your healthy. Buyers should consider their requirements and decide. If you find that you need this data and analysis at no subscription cost, then the Ring Air is a great option.

The Ultrahuman Ring AIR is one of the latest fitness tracking rings on the market. It arrives very competitively in size, weight, features, and best of all, subscription free. I have worn fitness tracking devices on my wrist off and on over the years, but never have I considered a fitness ring. As someone who has never worn a ring, this has turned out to be an interesting (and mostly positive) experience! In the Box: - Ultrahuman Ring AIR (Sizing done prior to purchase) - Standard Ring Charger - USB-C to USB-C Cable (1 Meter) Setup: Sizing will be done prior to ordering your ring. Ultrahuman can provide a free-of-charge kit with all their pre-selected sizes. I would highly recommend trying some of the sizing rings on different fingers to see what works best, especially during sleep, as this is where some of the best data comes from. Once you receive your actual Ring AIR, you will be prompted to create an account on the app and charge the ring prior to setting up so that any software updates can be done successfully. The app setup was clunky as a couple of the screens to set your current body data (height, weight, gender, etc.) use scroll wheels that if not used precisely will bump you to the next screen. I had to restart the setup process to fix the error in data input. Frustrating. After downloading the app and account setup, I let the ring charge and completed the software update, which only took about a minute. Charging takes anywhere from 15 minutes to 2.5 hours depending on the state of charge. During my testing, I let the ring get to 15% and charged it to full which took just over 2 hours to complete. Upon first glance, app is overwhelming with data and its layout. Over the week of testing, it became less overwhelming plus the notifications helped with interpreting the data (caffeine window, sleep data, and reminders to move, etc.) Usage: As someone who has never worn a ring in their life, it was an interesting few days. I originally picked a size that I thought would work on both my index and ring fingers, but it turned out to only fit safely on my ring finger, no biggie. I chose the Raw Titanium color based on the samples inside of the sizing kit. I think this contrasts slightly less against my skin than the darker gloss or matte colors. I really like it. The ring is extremely light and small. After getting used to wearing it for a couple days, I often forget I am wearing it at times. The best part about it is that it doesn’t interrupt my sleeping by being uncomfortable like a wrist worn tracking device is. I don’t believe I lost any sleep because of comfort, even the first night. Battery life is good but depending on the mode you select, it will vary. I initially selected “Turbo mode” which is constant tracking of vitals and sensors on the ring. This used 25% battery in just 4 hours. This prompted me to change it back to “Chill mode” which is the default out of the box. This netted me 4 full days (day and night) of tracking with 14% battery left before I decided to charge it. Charging took just over 2 hours. There are options to “background sync” and “airplane mode” which impact battery life as well. I like having background sync enabled because it means the app is always ready with your latest data and doesn’t need to refresh upon opening it which takes 3-6 seconds typically. I would expect anywhere between 1 – 5 full days of tracking depending on what mode and settings you have enabled. When it comes to the data and how accurate the data is, I will say there is some variance to the ring’s performance. Some of this comes from the ring itself rotating slightly on my finger so that the sensors might not be in an ideal location for data collection. This has occurred during mowing where I am constantly changing the mowers direction. Outside of this, I think this is some accuracy discrepancies when it comes to other types of fitness trackers for step counts with the ring reading lower than wrist worn devices. I also wish the heart rate sampling was taken more often in “Chill mode” as there are sometimes large gaps in data on the graph which seems too excessive. I really have enjoyed the sleep tracking aspect of this ring given it has been very accurate with times (starting and ending), sleep stages, and recommendations on ways to improve sleep quality. Overall: I never thought I would enjoy wearing a fitness ring like I have with the Ultrahuman Ring AIR. I was someone who wore a Fitbit for a couple years, but I wasn’t one to wear it at night due to comfort issues and its general comfort wasn’t great. With sleep tracking a valuable piece of data, I decided to ditch the entire fitness device idea. With the opportunity to try this Ring AIR, I am back in the fitness tracking game with the added benefit of sleep tracking. I never thought I would be one to wear a ring, but this would be my go-to strictly for comfort and sleep tracking even if the daytime data isn’t as accurate. Pros: - Small, Lightweight - Attractive Design - Sleep Tracking Data - Qualifies for HSA Purchase Cons: - Step Count/Data Accuracy - Battery Life (Turbo Mode) - App Setup/Layout - Scratches Semi Easily

I was curious to see if this ring could actually do what it said it would do without charging me every month, as I've always been wary of wearable gear, especially smart rings.The Ring AIR surprised me with how light it felt right out of the box. My biggest worry going in was that it would be uncomfortable to wear all the time, but at only weighing around 2.4 grams and with just 2.4mm thick, it's fine. I opted for Bionic Gold finish, and to be honest, it appears more like a piece of modern jewelry than a smart ring.The titanium body with a tungsten carbide coating offers it a high end look that doesn't scream "fitness tracker" to everyone who sees it. I liked that they sent me a sizing kit first. It made the fitting process easy. I chose size 9, which felt snug but not too tight. After wearing it, I can confidently say I hardly feel it's there. The Ring AIR passes my test for comfort in wearables even when I'm sleeping, which has always been my test for comfort. The Good: What It Does Best Great Sleep Tracking This is where the Ring AIR really shines. Compared to other devices I've tested, the sleep tracking has been really accurate. It breaks down sleep stages like(awake, REM, light, and deep sleep) and gives you relevant information instead of just a bunch of numbers.Tracking my heart rate variability as I sleep has been really helpful in helping me understand how I recover. No need to pay for a subscription This is a big deal, so let me be clear. The Ring AIR gives you everything up front, whereas other smart rings charge you monthly fees. Yes, there are some extra features you may pay for, but the main experience is complete without any continuous fees. PowerPlugs Give You Actionable Insights The PowerPlugs function has changed everything for me. The ring doesn't just provide me statistics it also pushes me to make better choices. The caffeine window alerts have helped me time my coffee better, and the circadian rhythm tips have really helped me sleep better. It's like having a health coach who is soft on your finger. Full Health Monitoring The Ring AIR keeps track of a lot of different things, including heart rate, HRV, skin temperature, SpO2, sleep stages, and movement patterns. Keeping an eye on the temperature has helped me learn how my body reacts to stress and exercise. The Not-So-Good: Things That Could Be Better Inconsistent Sleep Tracking I praised the sleep monitoring before, but I have to be honest about the problems I've seen. Some nights the ring seemed to think I was sleeping for less time than I actually was sometimes by as much as 1.5 to 2 hours. It can be annoying when your attempting to find patterns and things don't always work out. How accurate is your heart rate during workouts? Monitoring heart rate during workouts been hit or miss. It's been trustworthy for casual activities like walking, but I have seen some inconsistent readings during more strenuous exercises. This isn't unusual for smart rings but it's worth noting if you care about workout metrics. Syncing apps and getting notifications When synchronizing data from the ring, the Ultrahuman app might sometimes be slow. Also, the notification system may be rather pushy, and its frequency can be bothersome at times. To find a balance that works for me, I had to turn down some. Battery It's okay, but not great, with a life of up to six days. I get the tradeoff because the ring is so thin, but I wish I didn't have to charge it as often. It's not a deal-breaker, but it's something to think about. Experience Using It in Real Life, The Ring AIR has really changed the way I live my life. The information about circadian rhythms has helped me figure out why I feel energetic at some times and tired at others. The recovery measures have helped me figure out how hard to work out, and the sleep coaching has helped me get ready for bed better. I've worn the ring in the shower, while swimming, and even while doing various water sports, and it has held up well. The hypoallergenic inner shell has kept my skin from getting irritated, which was a worry since I'm wearing it all the time. What you get for your money , The Ring AIR costs about the same as the other Smart Rings, but you don't have to pay for a membership. It gives good value for someone who wants to keep track of their health without the bulk of a smartwatch. The insights are really helpful, and the fact that it's comfortable makes it easier to keep track of things. The Ultrahuman Ring AIR isn't flawless, but it's a strong choice among smart rings For most users, its strengths comfort, extensive tracking, actionable information, and no subscription fees outweigh its shortcomings. The sleep tracking is not always perfect, but it gives me some useful information that has really helped me sleep better by changing my bedtime habits If you want a discreet and comfortable way to keep track of your health indicators and get gentle reminders to modify your habits, the Ring AIR is the way to go. Don't expect it to replace a dedicated fitness watch for serious workout monitoring. Be ready for some bugs with the app and data syncing. For me, it became a big part of my health regimen. The information has been helpful, the comfort is great and the fact that there are no monthly costs makes it a good longterm investment in my health tracking journey.

I have worn this ring for 2.5 weeks straight prior to reviewing it, taking it off (more than briefly to do things like washing my hands or applying lotion) only to charge it, and that only happened twice in the 2.5 weeks of use. I am a long time wearer of Apple Watches (and prior to switching to Apple Watches about 6 years ago, I wore various Fitbits), so I will be using that as a comparison throughout my review for the ring. As a caveat, I don't usually wear rings, so keep that in mind while reading my review - for someone who is used to wearing rings, some of my cons/complaints/concerns relate to the fit and comfort of the ring might not apply. Pros: - battery life - even on "turbo mode" (which, according to Ultrahuman, is supposed to drain the battery quickly) the watch battery lasted a full week without being charged! I can't even make it 24 hours on a single battery charge for my watch - lots of interesting information gathered from 1 single finger - from stress rhythm, temperature, sleep, UV/Vitamin D exposure...so much is being measured! Cons: - I need a half size, and I'm sure I'm not the only one who has or will run into this issue. I had the sizing kit, and the smaller size was just tight enough that it was hard to get off without some effort, but the larger size slipped off easily (especially when wet), which makes it hard to get accurate readings, according to Ultrahuman's directions (I went with the larger size because I didn't want the ring to get stuck on my finger without being able to get it off if needed) - It is bulky, awkward, and very masculine looking. Again, keep in mind I don't normally wear rings, but wearing it on my right finger completely prevented my pinky finger from lining up with my ring finger (pictured), and it was an annoyance throughout the day. - Easily scratched material - even before a full 24 hours of wearing it had passed I was noticing a lot of scratches on the ring just from every day wear and tear. After 2.5 weeks, pretty much the entire ring is scratched up, and I just don't think it would be durable to wear it all day every day until the ring needed to be upgraded or replaced. - The app. Oh, the app. It is a mess. There are 5 different "tabs" on the bottom of the screen - and only 1 is applicable to the ring. One is a Zones (Ultrahuman's social network - I didn't explore it since I didn't have anyone to connect to, but it looks like it is their version of how you can share your activity information on Apple Watches with friends), one is your "profile," and the other two are just there to try to sell you their other products. But that's not the end of the mess. The UI seemed very overcomplicated and busy, the graphs/modules moved around based on the time of day, and there's not a lot of explaining of what all of the graphs/modules were measuring or how to change them. - Accuracy of data. I am not entirely sure the data is accurate. I frequently spot checked things that both my Apple Watch and the Ultrahuman ring measured, and there were frequent major contradictions between them or things that I know for a fact were wrong (for example, the ring would say I was asleep while sitting on the couch watching TV even though I know I was 100% awake). I have been able to measure the accuracy of data from the Watch against actual medical devices (i.e., an oximeter for my pulse, sleep data against a sleep test, etc) and as a result generally consider the Watch to be accurate, so when I saw drastic differences in the data between the Watch and the Ultrahuman ring, I was a little weary. - Charge time of the battery - to fully charge the Ring from dead (or basically dead), it takes over 2 hours, and at least one of the times I charged it, I kept having to adjust the ring on charger because it would stop charging. I feel like this Ultrahuman smart ring left a lot to be desired for me. If you are wanting fun insights into your health (that may or may not be completely accurate), a smart ring might be the right move for you. Unfortunately, I think this one missed the mark, and I can't recommend it.

This Ultrahuman Ring AIR is an amazing piece of technology! First off, before you even purchase the ring, there is a sizing kit that you can obtain beforehand that contains plastic rings that help you size the ring perfectly and enable you to wear for as long as you want before committing to a purchase. That is a superb idea! When the ring arrived, it was in a very oversized box for the product size, containing the ring, the charging base, a charging cord and instructions. Charge up your ring right away, download the Ultrahuman app and set it up. It doesn't take long, you can import information from your iPhone/Apple watch etc. to help it get a head start on its metric taking. The first thing that I noticed was this, and the only reason throughout its use that has removed one start from the review. The actual ring you purchase feels almost identical to the plastic ring that I used to size and test fitment of the ring in the first place. There was literally no difference in feeling of the ring - which means the test ring is very accurate, however, with the ring being made of 'Fighter Jet Grade Titanium reinforced with a Tungsten Carbide Carbon coating' it sounds strong and durable, yet it feels, well, plastic. And the finish on the ring, while being 'Aster Black' is only black in certain lights, and is actually a lot shinier and reflective silver in color when you view it in normal light. I'm not saying that is bad, it's a great looking ring, but if you are looking for a 'black' version of the ring, this is not it. However, those are the only negatives at all, that I can find about the ring. I've had it for about 2 weeks now, taking it off only for a short time to keep it charged (and it does remind you that you aren't wearing it!). It is incredibly comfortable, so much so it has replaced my wedding ring's position on my hand. Very light and unobtrusive, feels great while wearing it. And the data it is capturing is fantastic! My sleep patterns are very detailed, letting me know how long I slept (which is no-where near long enough), how deeply I slept, whether I tossed and turned in the night and how many times. It tells me how hot my skin is, what my heartrate is, and how consistent it is over time. It takes about two weeks to fully update and get a good accumulation of data, but when paired with the Ultrahuman app, it really does a deep dive into your health metrics. As of the last couple of days, it has finally triggered an age metric (as I mentioned it does take some time to accumulate the data) and it suggests that I am 3 years younger than my actual age, which I assume defines me as somewhat healthy! It's been fun going down the rabbit hole of information, researching the new data points that I didn't even know what they were to start with along with interesting tidbits of info that it has provided in the two short weeks. There are action plans, workout options, that you can trigger, there is a comparison chart with your friends, so you can compare how each of you are doing if you invite other people to your list, all great features that go above and beyond the data points of the ring. That app sends you push notifications if you so choose, it will tell you when to cut out caffeine, when to actually take some caffeine(!), when to stand up and move, when to close the curtains and remove some light from your day so that you can start to wind down easier for your night's sleep - it's all pretty impressive! Overall, very impressed with the ring, it is capturing way more data about myself than I expected. The price point is somewhat high to begin with, and as mentioned, the ring is light and comfortable as well, which did make the ring feel a little 'cheap' initially, but the benefits of the data, and the free companion app are all great features of this wholistic product. I did notice that the surface of the ring has been prone to a few light scratches in the short time I've had it, but you can buy ring protectors that slip over the ring to protect it, should you need to. Loving the ring so far and look forward to continued data collection for my own gratification!

----- SUMMARY ----- Verdict: The Ultrahuman Ring AIR succeeds where many wearables fail by delivering genuinely useful health insights in a form factor you'll actually forget you're wearing. Its exceptional sleep tracking and Recovery Score provide actionable data that correlates remarkably well with how you feel, making it invaluable for managing daily energy levels. While step tracking isn't perfectly precise and the finish scratches more easily than expected during weightlifting, these minor drawbacks pale compared to its core strengths: effortless 24/7 tracking, subscription-free features, and an intuitive app with valuable "PowerPlugs" like the Caffeine Window. For anyone who's struggled with bulky smartwatches or wants comprehensive health monitoring without the hassle, the Ring AIR represents a compelling shift toward truly passive wellness tracking that actually improves your daily routine. Pros: - Lightweight and comfortable for 24/7 wear - Excellent for comprehensive sleep tracking and detailed analysis - Provides actionable health insights - Intuitive and well-designed companion app - Subscription-free core features - Good battery life (4-6 days) - Durable "fighter jet grade Titanium" shell - Medical-grade hypoallergenic resin inner coating - Water-resistant up to 100 meters - "PowerPlugs" for customizable health tracking - Seamless pairing process Cons: - Step tracking can be slightly imprecise - Finish susceptible to scratches, especially during heavy weightlifting - Charging dock LED indicator light is always on ----- DETAILS ----- Design, Comfort, and First Impressions: The Ultrahuman Ring AIR delivers a premium unboxing experience from the start. The clean, white packaging is reminiscent of opening a high-end tech product, revealing the ring, a compact wireless charging dock, and a quality braided USB-C cable. However, before you even get to that point, I can't stress this enough: start with the sizing kit. Best Buy often offers a deal that essentially makes the kit free after a gift card, so there's no reason to skip it. I'm glad I followed the advice to wear the sample sizer for two full days and nights. My initial choice in the middle of the day would have become uncomfortably snug overnight. Our finger size naturally fluctuates with temperature and hydration (a factor especially noticeable here in Phoenix), and the extended test definitively pointed me to the larger of my two potential sizes. The final Ring AIR fits exactly like the sizer, which is a testament to their process. Upon handling the actual ring, the "AIR" in its name immediately makes sense. It's astonishingly lightweight, weighing just a couple of grams. After the first two days, I genuinely forgot it was on my finger. This is arguably the most significant advantage of a smart ring. When a device becomes unnoticeable, 24/7 tracking becomes effortless. I've always struggled with tracking my sleep with a smartwatch. They're either too bulky to be comfortable or need to be charged overnight, defeating the purpose. The Ring AIR solves both issues beautifully. The ring itself looks and feels premium. Ultrahuman boasts about its "fighter jet grade Titanium" shell, and while that's great marketing, the real-world feel is one of solid, lightweight construction. The inner surface, coated with a medical-grade hypoallergenic resin, is perfectly smooth and has caused no skin irritation. While one side of the ring is flattened to house the sensors, it's completely unnoticeable during wear. Plus, with a water resistance of up to 100 meters, there’s no need to worry about taking it off for swimming or showering. A word of caution for weightlifters, however. I recommend removing the ring when using barbells or dumbbells. Not only can it be slightly uncomfortable, but despite its durable claims, the finish is susceptible to scratches. I noticed a few minor scuffs after one session and have taken it off for every workout since. This is a trade-off to consider if you want to track metrics during resistance training, for which I still rely on my smartwatch. Based on appearances, the "Raw Titanium" finish would likely be the most resilient against visible scratches. Actionable Health Insights: For such a diminutive device, the depth of its health metrics is truly impressive. The ring’s sleep tracking provides a nightly sleep score, but its real value lies in the details behind that number. It breaks down contributors like sleep duration, resting heart rate drop, temperature variation, and timing, transforming a simple score into an active tool for better rest. It even captures subtleties like how many times you toss and turn and provides a clear view of your sleep stages (REM, Light, Deep). I've found a strong correlation between my score and how I feel the next day, which has built a lot of trust in its analysis. When it comes to activity, the Ring AIR tracks the expected metrics (steps, distance, and calories) but presents them within a "Movement Index." I appreciate that this score rewards consistent, all-day activity rather than just a single, intense workout. As someone who can easily get locked into work at a desk, it's a powerful reminder to stand up and move throughout the day. The step tracking, however, isn't perfectly precise and tends to count more steps than my smartwatch. I see this as not a flaw, but as an inherent trait of a ring-based tracker. It's difficult to distinguish every hand gesture from an actual step. I view it as a directional guide for an active lifestyle, not a clinical pedometer. The Recovery Score was a new feature to me and quickly became one of the most valuable. The score synthesizes biomarkers like Heart Rate Variability (HRV), resting heart rate, and skin temperature to tell you how ready your body is to perform. The connection between this score and my subjective feeling is undeniable. Pushing through a tough workout on a low-recovery day leaves me feeling depleted for days. As a dad to a young daughter, understanding when my body needs to prioritize rest isn't a luxury. It's essential for being present and energetic. Heeding the advice to swap a high-intensity session for a light walk has had a profound impact on my overall well-being. The Ultrahuman App & Ecosystem: The Ultrahuman app is the central hub for all your data. Pairing via Bluetooth was a seamless, guided process that took only a few minutes. At first glance, the sheer volume of information can feel overwhelming. However, Ultrahuman has designed a clean, sophisticated interface that presents key insights on the main screen, while allowing you to drill down into specifics with a simple tap. It’s like a dashboard for your body, turning complex data into easy-to-understand, gamified scores that motivate you to improve. A standout feature is "PowerPlugs," a library of add-on modules to customize your experience. You can track your "Caffeine Window," monitor Vitamin D exposure (a very relevant feature living in sunny Arizona), and much more. I'm a huge fan of the Caffeine Window, which recommends optimal consumption times based on your sleep data. Simply delaying my first cup of coffee and having a firm cutoff time has noticeably improved my energy levels and sleep quality. Most of these PowerPlugs are free, keeping the core experience subscription-free, a major advantage over competitors. A few advanced modules, like AFib Detection, come at an extra cost, but they are entirely optional. Battery Life & Charging: The Ring AIR boasts excellent battery life, consistently meeting the advertised 4 to 6 days on a single charge. I primarily utilize the "Chill Mode" within the app, which strikes an optimal balance between data collection and longevity, providing 5 to 6 days of use. For more frequent readings, "Turbo Mode" is available, though it reduces battery life to approximately 4 days based on my experience. Charging is simple with the included dock. A full charge takes about 1.5 to 2 hours. My only minor gripe is with the charger's design. The LED indicator light is always on, which can be an annoyance in a dark bedroom. I've taken to hiding the dock behind a lamp, which feels like a workaround for a design oversight. A simple option in the app to disable the LED would be a welcome improvement. ----- WHAT’S IN THE BOX ----- 1 x Ring AIR 1 x Ring AIR Charger 1 x USB-C Cable 1 x Quick-Start Guide 1 x User Manual

I’ve been using the Ultrahuman Ring for a while now and overall, I’m very happy with its performance. The ring works really well in measuring health metrics — accurate, consistent, and very insightful for tracking my daily activity and recovery. That said, the matte black finish seems to scratch quite easily. For a product in this price range, I was hoping for a bit more durability in the exterior coating. Functionality-wise it’s excellent, but the appearance starts to show wear sooner than expected. If Ultrahuman can improve the coating quality, this would easily be a near-perfect product.

My experience with the AIR has been mostly positive over the time I’ve spent with it. My first impressions are this is a very nicely designed product and the company is committed to making this product successful. USAGE—You need to wear the ring for a while so it can learn your body. Once it does learn your body the app will provide you with a lot of data, maybe too much if you are not ready. Within the app it tries to explain some of the metrics but at times I found the explanation of them to be confusing. The ring has multiple battery usage modes: Turbo, Chill, and a low power mode. I stared with the ring on Turbo to get the most initial data at first and did not experience any battery issues. On Turbo you will definitely get the worst battery life so Chill is recommended. Using chill I have easily achieved 5-6 days of usage between charges with the latest firmware update. This is where the “in-progress” comes in since I’ve received the ring I have received multiple firmware updates and with each one came its own issues. Luckily Ultrahuman appears to be on top of making the AIR a better product with each update and are very quick to fix any bugs/issues that arise. DESIGN— The titanium is sleek and the ring is very comfortable to wear. The packaging is minimalist but very well executed. In the box you will receive the ring, charger and USB-C to USB-C cable. There is not a block included so you will need to supply your own, which is not too much to ask at this point. SETUP— After reading the quick start and following the initial instructions my ring quickly paired with the app and my phone.

First impressions - a total waste of space for packaging. I've taken pictures with an Apple TV remote there for scale. This huge box has nothing but a small ring, a small box with a USB cable in it, and the small charger. Got the ring changer powered up and put the ring on there. It is very obvious which way to orient it, as the charger has the flat spot for the part of the ring where the inner surface is fattened by the sensors. I downloaded the app via the QR code included in the small "getting started" pamphlet. I opened it up, and apparently the only options for an account are Apple or Google. No option to simply use an email address. Once I got past that, and continued the pairing process, it found the ring easily enough and was ready to "start my journey" apparently. The annoying part was entering weight and height. Now option to simply type. You have to spin the annoying dial which goes about 4 lbs. per swipe. If you have a bit to change from the default 130 or whatever lbs. they show, you will be playing for a while... There is no momentum, and if you accidentally come off that curve of the dial (swiping straight across rather than the curved edge of the image of the dial) it jumps you to another page, and you have to swipe back again to continue the chore. This was annoying enough to lose a star out of the gate. No reason to have a simple number entry option. Once I got past all the personal details, it finally got to the point to offer a hardware update. Fortunately, that took less than a minute, and the ring rebooted automatically. I like the fact that it is water resistant up to 100m (330 feet) and I haven't dived or done scuba since my time living in Europe over 35 years ago, so for me it won't be a limiting factor. Once you get past the intro screens about the features, you're dumped into the app. Main page shows boxes for movement, stress rhythm, sleep, sleep debt, and caffeine window. All show "no data" since it hasn't picked up any yet. There is also a spot for breathwork, or workout. On the very bottom you get readings like heart rate, skin temp. The charger now showed green, which I assumed meant my ring was fully charged. Time to play. Placed it on my finger, and began moving around for the afternoon in my normal after work activities. This was a Friday afternoon, so I figured I have plenty of time of normal things before I'm sitting at a desk again. By Saturday it had data and was reporting things. But some of it was odd - telling me to avoid sunlight and not be active anymore by 4:21 PM already? Seems a bit excessive trying to make sure I can sleep well tonight. But I keep thinking about it as an activity tracker, when really, it's a sleep and recovery tracker at its core. Which is why the main things in the window are warning you when to stop drinking caffeine, when to start winding down so you sleep better, etc. You really have to dig to get things like steps and such. Over the course of a few days, I'm finding this seems to be off by about 7% from activity tracking on my Apple Watch. My steps seem to be less on this than on the watch. From some of the things I'm finding from others, the discrepancy isn't a rare thing only impacting me. But I've no definitive way to know which one really is more accurate, although even an old fitbit was much closer to the Apple Watch data, so I'm thinking the accuracy is likely to be in that end of the spectrum, despite the fact that tracking activity on the fingers is supposed to be more accurate than the wrist. Battery modes - a bit of confusion here for me. "Turbo Mode" is the high battery usage mode. All sensors, all data, for continuous all day tracking. Chill mode (default) - focuses on tracking during sleep and restful periods to extend battery. This focuses on the sleep and recovery and supposedly movement. But it does not way what it stops doing anywhere I could find. Critical battery mode - "Strips it down to essential motion tracking." Again, seems like it just is tracking motion then, but what? Steps? Kcals used? How and what does it actually track? Obviously, there are no actual details of just what aspects are really tracked or ignored in each. I would like to know more details, and the app doesn't specify. At some point I'll have to hit up a web search to find out. You do have the option to turn off background sync though, where it automatically updates the app in the background all the time. I'm working with that disabled since I only need to see the data when I open the app, and I don't mind waiting for it to sync at that point. And I've had it in Turbo mode just to try to gather all the data I can. There's a "Find my ring" feature in the app that's about useless. It finds nothing until I'm within a foot of it. Heart rate - Strangely enough, this is wildly inconsistent. By the time I was wearing the ring for 24 hours, for some reason about 9 AM until 12:30 PM, it just didn't have any data. I was active at that point, moving items around my house for some work for redoing my basement, and even cutting the grass for my entire yard with my push mower. No readings at all. There is a bit of upselling in the app, and one of the things I saw was a protection plan in case you lose weight and need a smaller sized ring, you can get a one time changeout. Handy option for something primarily designed for sleep, not weight loss. But since it does track activity, albeit somewhat reluctantly and erratically, it may be OK. I was hoping for a good alternative tracker to supplement my Apple Watch. This isn't quite what I had expected (my own fault for not digging deeper when I was looking at it) but I think ultimately it will do fine. I have to take my watch off a few times a day since I don't charge it overnight, as I use it for sleep tracking as well. But since this ring is actually DESIGNED for sleep tracking, I can keep the watch for the daily activity tracking, and let this focus on my sleep tracking. This may be a much better pairing than I had expected. The following morning after turning on Turbo Mode, my battery had only dropped 3% over the course of 12 hours. That is actually less than it dropped the initial day on the default mode. I'm assuming because this was a sleep period, so at 8 AM it was at 71%, but today was going to be a very active day as I'm redoing some of my basement and have a lot of shelving to haul downstairs and things to move out of the way down there. 6 1/2 hours of heavy work, tons of up and down stairs, carrying things to the basement, and all the work starting the basement changes I wanted to begin today, the battery dropped only 4%. So turbo mode doesn't seem to be too horrible in my view, since I'm used to charging the Apple Watch every single day, usually a few times a day keeping it topped off. Another 15 hours later, including seven hours of sleep, and the battery still in turbo mode was down to 58%, a loss of only 9% in that time. 10.5 hours later, 53% 24 hours later, 42% after an afternoon and evening full of activity. At this rate in Turbo Mode I'll get 5 to 6 days of use before I have to recharge. Not a bad thing from my point of view, but certainly not what is advertised. But that's why the middle setting is the default setting. I'll just have to do some web searches to find out EXACTLY what is enabled and disabled in each power mode. But then there was a total reversal of battery usage. Up to this point it seemed pretty stable, but suddenly it went from 100% last night before bed, to just 73% this evening, less than 24 hours later. So I don't know why now this wildly inconsistent and unreliable as far as battery usage goes. On the days that I had more activity than I'd usually get in a whole week due to my basement project, it lasted fine, but on a day that I sat at the office in my chair working on things for 8 hours straight, it dropped 27% when there was no activity other than sleeping, then a full day of typing and mousing. The ring itself has been comfortable, if snug. I've had no issues from wearing it non stop. No sharp edges anywhere. And so far seems to at least hold up to the things I've been handling since I have no scratches despite all my work in the basement the last five days now. Today I checked again, ring shows 8% less steps than the watch, and it was a very busy day at a client with a lot of walking. There are things that it says it won't be able to calibrate since some things require 7 days to gather enough data. But I like the sleep tracking, it's more comprehensive than the Apple watch. Since it's tracking everything, it keeps a running tab of "sleep debt" for you, so you can see how you're actually coming into what would be considered healthy sleep patterns. I'm currently at a 20 minute debt. So for an activity tracker, I'm not sure. I've had other things for tracking that were usually within 1 to 2% of my Apple Watch tracking, so I'm just not sure the accuracy here is what I'd use for tracking steps and such. And since it has entire swaths of heartbeat data that it missed, again, not sure about that. But since it's actually designed for sleep tracking, and recovery and such, so far, I see it really seems to do well in that area. From now on the Apple Watch can charge overnight, and this will handle all my sleep tracking, and we'll see how it goes.

I ordered this ring because I wanted to wear something that isn't as pronounced as the the traditional fitness bands and because I prefer to wear an analog watch and it always felt weird to have two time devices on my hands at the same time. I was worried the ring wouldn't give me as much information or be as accurate, but all of those worries were completely unfounded. I used the sizing box and wore the test ring for a couple days to make sure the fit was what I was looking for in something that will be on my hand constantly. They also provided sample metals so you could tell what each style would look like. The ring came in exactly as I'd ordered and fits just like the sizing ring. It comes in a fairly large box for being a ring, but it's not a bunch of wasted space or material. The ring is safely in the middle so avoid getting damaged and pulls right out. That section pulls out and exposes the charging station along with some basic paper instructions. The charger is compact, USB-C, and grooved to ensure you set the ring on it properly. The paper instructions come with a QR code to get the app. I had no issues getting or installing the app on my phone. I was not a fan of having to use Google or Apple to register, but I have both so it wasn't a huge issue. I would have preferred to use a private e-mail account, but never saw the option to do so. The ring is comfortable, easy to wear for long periods of time, and I wore it to the lake this weekend and have had no ill affects from the water at all. In fact, I've only taken it off to charge it once since receiving it over a week ago. I'm impressed with its durability. If you think it's a simple fitness tracker, you're sadly underestimating the power this thing wields and the data it gathers. It gives pointers for sleep, caffeine, HRV, and dozens of other stats that I haven't even figured out how to evaluate yet. All that in a ring that blends into any outfit and looks nice enough to wear to anything. Also, for comparison I wore a couple other trackers and compared the data to what the ring was recording and they all match pretty closely. I think the ring does better step counting when carrying things, but all 3 were within a couple hundred steps of each other so I feel accurate. A general overview. Pros: 1. Very lightweight and comfortable. 2. Tons of useful information I've not found concentrated in other single trackers. 3. Durable. Worn in water, while doing minor carpentry, and while doing electrical. 4. Good battery life. Longer than most trackers between charges (the more often you connect the app the more it'll drain battery, but a few times a day and I'm getting over a week between charges). 5. Aesthetics. Looks like a nice ring instead of a tracking device. 6. Easy to install and use app (with the negatives about it written below). 7. Great highlights and recommendations based on activity (or lack thereof) and other statistics. I'm used to the activity part, but heartrate monitoring to limit caffeine, sleep improvement recommendations (when to wind down, when to stop eating, etc), and circadian rhythm information is a plus. I'm still learning new things about the data. Cons: 1. The app requires a Google or Apple account. 2. The app has a lot of functionality that requires additional purchases. They're not pushy about it, but I'd say half the app is dedicated to other options. 3. The nature of it being a fixed ring means any weight loss or gain is going to potentially make it useless for the wearer significantly sooner than the life of the ring itself. As you can tell, I have nothing negative to say about the ring or operation itself and the app issues are nitpicky in my opinion. I'm truly impressed with this thing and hoping it lasts a long time. At this point, if I lose enough weight to require a new one, I will plan on ordering it for sure. I kept the sizing box just for that reason.

I have loved this since I received it. It looks amazing, is comfortable and provides more stats than I know what to do with! That could be a good or a bad thing for some people but I love stats so the more the better! Setup: The device comes in a nice looking package. It will have a braided charging cable, your ring and a charging dock. Setup is simple as you only need to charge it and install the app on your device for pairing. You initially will not receive much data as most of the data is fully available after a few days. Style & comfort: I received my unit in Aster Black. It is a shiny blank that is slightly more thick than a traditional ring. I decided to wear it on my ring finger where it fits nicely and does not interfere with much. I have to be a little more careful when grabbing things though as the ring is made of titanium and is harder than many other materials. For example, when I open my car door, I am more careful what part of my finger grabs the handle so I don’t scratch the paint, the same with when I hold a phone or tablet without a case as the ring might scratch glass (I scratched a watch face with it by accident). The ring is extremely light and feels almost plastic, but this is because of the titanium build which is extremely lightweight. So far, I am very impressed in this category. My only complaint is that this color attracts fingerprints and smudges very easily. I have received no scratches in a week of use. Battery life: I have worn this for a week and charged it once. I have it set to the default battery setting which uses the most battery when sleeping or exercising, otherwise it sips battery throughout the day. It took about four days for mine to get to the point where I needed to charge it. App usage: The app is extremely robust. It is almost too much data for some people. Of note, I enjoy the circadian rhythm tracking, caffeine window (more on this later), sleep tracking, and recovery. There are other metrics which I don’t need such as Brain Waste Clearance, and more with the ability to use “Powerplugs” which are essentially free and paid extensions which add additional tracking like jet lag, ovulation, vitamin d and more. I love the caffeine tracking, as it shows the best time of day based on your metrics to consume caffeine for the greatest effect. I also like the Vitamin D tracking which does require a bit of extra input, but it allows you to track best times for sun exposure based on UV exposure and provides guidance. The app includes a section called “Ultrahuman Digital” which includes mediation sessions, workouts, sleep sounds and stories, podcasts and more. For those who might be in need of a continuous glucose monitor (GCM), they have an extra service for sensors and integration which can be extremely useful for metabolic fitness. Also, there are loads of 3rd party integrations for most popular services including MyFitnessPal, Garmin, Fitbit, Withings, Peloton, Health Connect and more. Of note, there are optional subscription options which I deem to be actually useful. For a fairly cheap price, one can get extra value on trade ins, theft and loss coverage, weight loss coverage where they will replace your ring if you lose weight, damage protection, and more. The cost is only

I've been using the Ultrahuman Air smart ring for a few days now, and overall, it's been a great experience. Here's a breakdown of my thoughts: Pros: -Perfect Fit: The sizing kit worked flawlessly. The ring fits snugly and comfortably. -Comfortable Material: As someone who’s never worn rings before, I was surprised at how quickly I got used to it—just a day or so. Outside material is elegant, I selected the Aster Black to match my usual color styles and I felt this was a good fit for me. Inside material seems to be like an acrylic overlay to cover the sensors with a clear material which I am assuming is part of the water resistance seal. -Sleep-Friendly: Compared to a smartwatch, this ring is far more comfortable to wear during sleep, which is a big plus for overnight tracking. With smartwatches, I found my self waking up more during the night since it was awkward if I found myself laying on the watch. I have not had this problem with the ring. -Comprehensive Metrics: It tracks steps, heart rate, skin temperature, sleep, and other activities. The insights and analysis help you understand how to optimize your recovery and energy levels. With an iphone, the app also askes for permission to write the data to your health app. So steps, sleep metrics, heart rate, etc. will also sync to the health app. -Recovery-Focused: The ring and app work together to analyze how factors like caffeine, sunlight, and sleep affect your energy, helping you make smarter lifestyle choices. -User-Friendly App: The app is easy to use and the ring was very easy to sync up. You can activate plugins that are relevant to your goals. -Smart Reminders: The app sends helpful nudges—like when to stretch, your ideal caffeine window, and the best time to get sunlight. -Water Resistant: I've worn the ring while washing my hands and even swimming in a pool about 5 feet deep—no issues at all. Cons: -Sleep Alarm Limitation: The only minor downside is that the sleep cycle alarm feature requires the app to stay open in the background, which can slightly drain your phone battery. Final Thoughts: If you're looking for a sleek, comfortable, and insightful wearable that prioritizes recovery and wellness, the Ultrahuman Air smart ring is a solid choice. It’s especially ideal for those who want to track their health without the bulk of a smartwatch.

Years ago, I used to wear a smart watch, but I quickly learned the downside of having a small version of a smartphone on my wrist and wanted to be less connected. I ended up replacing my smartwatch with a health tracking watch, but noticed it lacked a lot of the technology a smart watch provided. When I learned of a smart ring which provides a plethora of information to fill that void, I was excited to try it. This ring is designed to be used on either the index, middle or ring finger. I choose to wear my ring in place of my wedding ring since it is more comfortable and stays in place. I also choose the Aster Black color and could not be happier with the finish and color. I have been wearing this ring for about a week and have been pretty amazed with all the data and suggestions the app provides. Unsurprisingly, I noticed the step counts and fitness tracker varied slightly from my watch and phone. However, no tracking device is perfect. How you use the data to make healthier lifestyle choices is the most important aspect. The app is amazing and I was thrilled there were no monthly/yearly subscription fees. Ultrahuman provides so much information on their app, but makes the data not seem overwhelming. The color choice for each section and the ability to choose what data you want to access makes the data more valuable. I also am a big fan of the suggestions the app gives to help improve the scores. The only improvement I would like to see would have an option to charge the ring when it is on the finger. The battery life only lasts a few days and data is missed when I am not wearing it. I would highly recommend this ring. The data it provides is very useful, the app is thorough and organized, and all of this is provided without needing another subscription.

I have had a smart watch for several years. I was a little skeptical about a ring that could track my health. This is very fashionable, comfortable and tracks way more than my watch does! I am still figuring out all the aspects of the app. It gives me my sleep stats (similar to my phone). I am also alerted to the "closing of my caffeine window" in the afternoons to know when caffeinated products may affect my sleep. It also tracks sun exposure to be sure you get enough Vitamin D. I have to enter it manually. It doesn't seem to sense it. It also tracks your body temp, heart rate, and circadian phases. There are several "PowerPlugs" you can add to customize your ring. The options include, Vitamin D, Screentime, pregnancy insights, cycle and ovulation among others. Some require a monthly subscription. Those include weight loss, and social jetlag. The last one tracks any misalignment between your circadian rhythm and work/sleep schedules. I like that I can wear this at all times unlike my watch. I wear it swimming (pool or ocean), showering etc. The charge also lasts about a week. My watch requires daily charging. Overall, this is a nice way to track health that just looks like normal "jewelry". I have the titanium finish. It does show some wear after about 2 weeks of daily wear. Overall, this is a great way to track multiple aspects of your health
