Customer Ratings & Reviews

I’ve now had the Ultrahuman ring for a few weeks and I wish I’ve had this my whole life! The first thing I noticed is how lightweight the ring is, you really don’t even notice you’re wearing it. It matches the rest of my gold jewelry and really looks like a simple gold ring. It's very durable and is yet to show any sort of wear and tear. The layout of the app is easy to follow and organized. It is practically identical to its competitors but much cheaper and offers additional features. My favorite thing about the ring is that you can initiate the tracking of workouts, and it will appear on your phone. This is super helpful when I want to compare the workouts I do to my total activity for the day. I’ve also enjoyed tracking my sleep and circadian rhythm. These two features, along with the ability to track your caffeine window, have all helped me build a routine and feel more energized as a result. The battery life is impressive, I can go almost a week without having to charge it. And when I do need to charge it, it reaches 100% battery quickly. Overall, I will be recommending this ring to many of my friends with different lifestyles. This ring is the best way to track your health and wellness and avoids looking like a distinct piece of wearable technology.

I’ve really been enjoying my Ultrahuman Ring. It’s sleek, comfortable, and the insights it gives on recovery, movement, and metabolic health have been incredibly motivating. I especially love how it integrates so seamlessly with the app and how detailed the metrics are. That said, I’ve noticed the sleep tracking isn’t always accurate. It sometimes logs time I’m just lying down or watching TV as actual sleep, which can throw off my sleep score and recovery data. I’d love to see improvements in how it distinguishes between rest and real sleep. Overall, though, it’s been a great addition to my health routine—and I’m excited to see how it evolves with future updates.

I’ve been using the Ultrahuman Ring and I absolutely love it! It’s sleek, super comfortable, and provides incredibly helpful insights into my sleep, recovery, heart rate, and daily activity. It’s helped me become much more aware of how my body responds to stress, rest, and movement. The app is beautifully designed and easy to understand not just data, but real guidance. It’s become a part of my everyday wellness routine, and I can genuinely say it’s worth every penny. As a woman going through menopause, I do wish the Ultrahuman Ring would offer more features specifically tailored for women in this stage of life like tracking hot flashes, hormonal sleep disruptions, and mood variations. That would make an already amazing product even more powerful and inclusive. Still, I highly recommend the Ultrahuman Ring to anyone serious about improving their health and well-being. It’s a game changer! Taciana Alcoforado

I was so excited about this ring and all its features but it’s very meh. Not accurate most of the time, even after wearing it for 4 months. Step count and workout tracking are useless. The sleep score is cool but I’m not even sure if that’s accurate. Wish I could return it but they have such a short return window on wearable items… which sucks when you need to wear it awhile to see if it’s a good choice for you. My sister got one at the same time and has gotten 3 replacements from UH because they stopped charging or wouldn’t connect to her phone. Just overall, not great. Thought this would be my Apple Watch replacement but it’s bulky, not accurate and overall underwhelming. It also scratches SUPER EASY and the gold color is giving costume jewelry.

I’ve had the UltraHuman ring for about 3 weeks so far and it’s quite interesting. It has a wide range of information that you wouldn’t know or find out by not having one. From body temperature, sleep tracking, steps in a day and much more. It also has a built in workout system so you don’t have to find them on the internet or anything. The down side is the battery heath which only last about 4 days and less if you keep looking at the app for information. Over all good and has a sleek look. I have the Aster Black color

I've been using the Ultrahuman Ring for a month, and I can't stop raving about it! This sleek, stylish ring has completely transformed my approach to health and fitness. I absolutely love the sleep alarm feature! It wakes me up after completing my selected number of sleep cycles, ensuring I start my day feeling refreshed and energized. It's a bit of an investment, but trust me, it's worth every penny for the benefits it offers. Overall, the Ultrahuman Ring has far exceeded my expectations. If you're serious about taking control of your health and fitness journey, this is a must-have.

This ring is extremely accurate and has helped me track my sleep way better. The insights have improved the quality of sleep significantly. Beyond sleep, it also helps me with coaching nudges. Pairs well with my phone, is super comfortable and has great battery life. Highly recommend!

Has a ton of great data, only one problem there are connectivity issues. Today is the 21st of Jan 2025 it has not synced since the 18th

I'm happy with the purchase only had a week it's still in calibration but the battery has lasted 4 days the data is still in calibration but also shows steps & active hours

The ring is very classy and I love reading the information about my stress and sleep, but steps are super inaccurate.

This is the best wearable device to sleep. Nothing even get close to, it just works!

I took this ring off to workout, shower, swim, or put lotion on etc. I didn’t want it to get scratched. And somehow it developed a bubble that eventually busted in the inside.

They did price match for me & it was awesome to get the ring from bestbuy instead of ultrahuman.

Buyer beware. My ring died after just 2 months of use. Followed all of the support protocols to no avail. Left with a dead ring, and no support. My suggestion, if you are in the market for a smart ring, research the support before making your purchase, and stay away from this one.

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

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.

Do you ever feel that you need some type of accountability for keeping healthy habits? The Ultrahuman Ring AIR does just that and more. First, a little bit of background. I am healthy for the most part, but something I do lack is keeping a consistent sleep schedule, and at times, not getting enough sleep. For a couple of years now, I have struggled to keep a consistent sleep schedule. This was due to various factors, but typically, I have prioritized other items over sleep. But in the time I have been using this ring, things have changed. I have been using this for about a week now, and wow, sometimes all you really need is accountability to get a healthy habit going. I just had the most consistent and longest time in bed this past week. And as surprising as this sounds, all it took was this Ultrahuman Ring to motivate me. On top of motivating me, this ring requires no subscriptions, which is a rare thing to say these days! In this review, I will go over my experience in using this smart ring. *TLDR at the bottom ================= IN THE BOX/SETUP: The smart ring comes nicely packed in a low-key white box. You will get the ring, a charging base to set your ring on for charging, a USB-C to USB-C cable, stickers, and some documentation. No charging brick is included, but a phone charger or a USB-C port on a laptop can be used. As a preface, this is my second Ultrahuman Ring, as my first one was faulty outside the box. This first ring would not connect to my phone or turn on at all. Luckily, Ultrahuman’s customer service was top-notch and quickly replaced it for me. You will need the Ultrahuman app to use this ring. You will also need a Google or Facebook account to sign into the app. While convenient, I would like to see other account options that don’t require you to connect an existing account. After going through a couple of setup steps and answering some questions, you will see the option to connect your Ultrahuman Ring AIR! The second ring arrived fully charged and connected to the app and phone quickly. It was up-to-date and ready to be used! This took about 10 minutes. ================= RING FIT, DESIGN, DURABILITY: Before buying this smart ring, I recommend using the Ultrahuman Ring AIR sizing kit. Best Buy offers this kit for $10, which also comes with a $10 gift card that can be used to purchase the real thing or something else. The sizing kit also has color samples so you can see all the colors that are offered. I decided to go with Matte Grey. The fit feels about the same as the plastic rings in the sizing kit. The ring can either go on your index, middle, or ring finger. I decided to use the ring on my index finger. I have no complaints about the fit, my hand has gotten used to the ring being there, and it almost doesn’t feel like I have it on. In terms of design, the outer part of the ring is made out of titanium, which the human body is biocompatible with. Titanium is a strong metal as well as a lightweight metal, which is great for a ring of this caliber. The outside is coated with a tungsten carbide coating, which, according to Ultrahuman, is resistant to everyday wear and tear. The inside is made out of epoxy resin, which should be hypoallergenic according to Ultrahuman. Physically, this ring is durable. I can attest to this as I have worked out while using the ring. While lifting, the ring does brush against whatever you are gripping, such as a dumbbell. I noticed there were iron shavings on the ring. I thought the ring had scratched, but after some warm soap and water, those shavings went away. In terms of physical durability, I am certainly impressed! I am more concerned about the software and battery durability. With some research, some have reported bricked rings after an update. I haven’t had a chance to install an update, but hopefully, this isn’t the case. Additionally, I am curious how long the built-in battery will last. Batteries naturally degrade over time; my concern lies with how long the ring's battery will last on one charge in the future. So far, I have charged the ring once after 5 days of usage. And this was on “Turbo Mode,” which is more battery hungry. Down the road, I can see one having to charge the ring 1-2 times a day, which can be a nuisance. Only time will tell. ================= ULTRAHUMAN APP: The Ultrahuman app has a simple UI that is easy to navigate. There are five “tabs” within the app, and about 2 of them are useful. The non-useful tabs are there to sell you additional Ultrahuman products, or if you have the product, connect them within the app. I wish you could hide the tabs, but I’ve been doing fine ignoring them. The tabs you will be in the most are the “Ring” and “Profile” tabs. The Profile tab is self-explanatory; this has everything regarding your Ultrahuman profile, like email, order history, and app integrations. You will spend the most time in the “Ring” tab. I love the UI here. Each tracking metric (e.g., movement, sleep) is separated into blocks. If you want more information, simply click the block, and more information will be displayed. I especially love how the blocks are color-coded depending on where you are currently with that metric. Green is good, orange is decent, and red is bad. This has been one of the sole factors why my sleeping patterns have improved this past week. The color codes are a psychological trick to get you to care for and work on whatever needs improvement. I am a gamer too, so treating this like a game has helped significantly as well. The ape brain says we must work and stay in the green! Another feature within the app is the ability to add an activity or task. Some of these are workouts, activities, food, breathwork, and more. I didn’t get a chance to use all of them, but the ones I did use, I will go into more depth in the next section. Finally, in the upper right corner is the “My Ring” section. When you click on it, you will get your ring’s status, battery, last known location, and battery usage mode are some of the items that can be seen here. I hope I don’t lose the ring because the “Locate my Ring” feature is terrible. After a couple of feet of walking away from the ring, the app loses the ring, and it lets you know the last known address of the ring, which won’t be helpful if you are in a populated area. Due to the internal space limitation, I understand why Ultrahuman didn’t add something simple, such as a small vibrating motor or speaker, to be able to easily locate the ring. The ring can also receive firmware updates, which can be installed within the My Ring section. ================= MY 1 WEEK OF USE: This past week has been a great learning experience when it comes to my health. My original intention was to use the ring for tracking sleep. But I have discovered that there is much to discover about my health. I will go through some of the information and general smart ring use here. I will start with sleep tracking. I can’t say how accurate this is, as I don’t have another device to test this out with but generally, the tracking seems to be consistent with when I go to sleep and wake up. A nice feature about this ring is that the ring can store data offline for a couple of days, which is great as I don’t have BT on the entire time. The app also gives you a recommendation of how much to sleep, which is located in the Sleep Debt section. Something else I have been tracking is Dynamic Recovery. This section lets you know how well you have recovered based on 6 metrics. Some of these metrics are heart rate, skin temperature, and a stress rhythm score. Yes, the app tracks stress, which I have noticed is sometimes inaccurate. At times, I am at my desk, and I take a look at the app, and the stress rhythm score is at a “Stress” level when I don’t feel stressed out at all. I haven’t figured out why this happens yet. I have also been tracking how much I move throughout the day, which can be tracked in the Movement section. I WFH a couple of times per week, so this one has been taking more work to improve. There is a minimum number of steps that the app suggests one take, and this is set at 11000, which is easier said than done. I do workout and that counts as “movement” in the app. But this needs to be tracked by manually activating it in the app. Once activated, the ring starts to track your movement using all its sensors at max. Using this mode is power hungry. But with this information, the app does start giving you more useful metrics, like giving you a Cardio age. I have strength trained with the ring on a couple of times, and it's not the most comfortable. You lack grip when doing some exercises, and sometimes the ring rubs on the bar, which is uncomfortable as the ring feels like it's being damaged. From now on, I will likely not use the ring for any strength training. Although this would be great for cardio, swimming, or any activity where your grip isn’t required. Here are some other items I didn’t get to focus on, but are available. There is a section where the app lets you know about the best time to consume caffeine. A built-in food tracker, which I did use for a meal, but noticed the nutrition facts were inaccurate, and there was no way to update the info. There is also something called PowerPlugs, which are additional features that can be enabled, such as a Vitamin D intake tracker and a screentime tracker. Some are free, some aren’t. There are more features that I couldn’t get to use during this week. It will surely take me some time to get through all of them. ================= CONCLUSION/TLDR: Overall, this smart ring has been a game changer for my health. Some data is inaccurate, like Stress Rhythm and at times, heart rate. The Ultrahuman Ring AIR has held me accountable to work on my health, and I hope it does so for a long time. On top of that, there is no subscription required! If that sounds like something that seriously interests you, I wholeheartedly recommend you give this smart ring a shot!

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.

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.
