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.

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!

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.

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’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

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!

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

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.

----- 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

Ultrahuman Ring AIR is a fantastic, discreet sleep tracking, heart rate, and temperature monitoring device that also offers a growing set of features without a subscription! Recently, I have taken interest in monitoring my health closer and tracking my sleep quality to improve recovery and overall well being. After years of on and off “watch” wearables previously, I was looking for something with less bulk, better battery life, and would be more comfortable during sleep. The Ring AIR is exactly what I was looking for, while being thinner and lighter than I anticipated. I used the Ultrahuman sizing kit to determine the best size, selected a 1/2 size up from my normal ring size and found the Ring AIR to be nearly identical to the sizing ring in fit. The ring is packaged in a somewhat large box for the contents; inside you will find a nice long braided USB C cable, charging dock, and naturally the Ring AIR. Ultrahuman does not provide an AC adapter but this is fairly common and less wasteful. After a brief pairing and letting the ring fully charge, you can start wearing the ring. The Ring AIR seems well constructed with tungsten carbide coated titanium exterior and a polished hypoallergenic resin interior that is quite comfortable. I often do not notice I am wearing the under 3 gram ring, as there isn’t much interaction with the device itself. The raw titanium finish I opted for looks even better than the sample in the sizing kit, though it is already showing some light scratches after 2 weeks of wear. Battery life has been pretty good for me, lasting 5 days on Turbo with background sync enabled. The charging dock has a status light to indicate if the ring is charging, fully charged, or not detected; which unfortunately emits a constant purple light when not in use. The dock does not contain a battery and fully charging the Ring AIR can take 90 minutes. For my use, I have switched to shorter and more frequent charges when showering instead of waiting for a full charge every 5 days. The Ring AIR is also water resistant to 100M, so should handle daily activities without concern. Moving beyond the device, the bulk of your interaction and insights are found in the well designed Ultrahuman app. Here you will find your movement and sleep tracking data, heart rate, and temperature, as well as unique feed back and insights such as Stress Rhythm, Dynamic Recovery, Ultra Age, and more! Ultrahuman continues to iterate and provide additional feedback through “Powerplugs”, which can be added at no cost, though some such as AFib Detection (not currently available in US) have a fee in what would otherwise be a subscription free experience. As you wear the Ring AIR, the app analyzes your data to provide useful insights as well as explaining what it indicates and actionable items to improve outcomes. The app will suggest tagging certain activities and metrics, and seems to improve overtime in accuracy. Overtime the app will learn your baselines and based on your activities, offer advice on how to improve your scores. I really like all the feedback and data trends the app provides, while the interface is easy to use and understand. You can also link the app to external sources, such as Apple Health, for consolidating and data sharing. After a couple of weeks of wear, the Ring AIR has provided excellent sleep and movement tracking along with detailed insights and correlations I never considered before. Though some additional features are behind paid “Powerplugs”, 99% of metrics I would want to track are covered without a subscription cost. I really prefer to just purchase a device and not have to worry about on going fees to access your data. The Ultrahuman Ring AIR delivers on this while continually improving their already fantastic app, making this an easy recommendation for anyone who is interested in a wearable that is more than just a tracking device.

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 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.

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

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.

The Ultrahuman Ring Air is a lightweight smart ring that can track health and exercise related metrics. Since it’s lightweight, it feels comfortable when wearing all day. The ring looks good and feels comfortable. The battery is small, but lasts for days. With multiple power options, I can have it run at full capability which tracks alls stats that it can track. I can also choose a less power intensive option which extends use before having to recharge, but tracks all but a few metrics. There is also a power saving mode option as well. App Untrahuman has an app to use with the Ring Air. It’s where I can see the everything that is tracked by it. It’s very easy to use and looks good. It’s easy to find what metric I want to see when I want to see it. It also syncs automatically with the ring. Use The ring is very lightweight. This helps with comfort. I have found that, at times, I didn’t notice I was even wearing the ring. Just like any ring, it is possible for it to turn a little to the left or turn/spin to the right. This has happened to me from time to time resulting in me have to turn it back so that the sensor, which is on the bottom inside of the ring, faces the underside of my finger. If the ring was smaller, I wouldn’t be able to put the ring on, so I have the correct size. It’s just something that I now periodically check once or twice a day. Sizing I used the Ultrahuman ring sizing kit to determine the right size for the finger I use with the ring. The ring was reflective of the sizing kit’s ring. I ended up getting size 10. The Ring Air fits as I expected it to based on the ring sizing kit’s size 10 ring. Metrics The metrics tracked by the Ring Air seem to be accurate. I compared it to a smart watch that I have. Both were in line with each other. The Ring Air had good accuracy. Unlike a smart watch that can shift on my wrist enough to cause a problem with it tracking things, I didn’t run into that problem with the Ring Air. Final Thoughts I’m happy with the Ultrahuman’s Ring Air. I’m glad I have it. I think it looks good. It’s lightweight which lends to it being comfortable to wear all day. The battery has lasted for 4.5 days so far and should go for a few more days before I have to charge it. Ultrahuman includes a heavy duty USB-C to USB-C charge cable and a charger to set the ring on which doesn’t take up much space. If you are looking for a smart wearable to track health metrics, then I would recommend considering Ultrahuman’s Ring Air.
