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 been using the Ultrahuman Air Ring for a bit now, and I’m honestly impressed by how much this tech can do. It’s sleek, lightweight, and super comfortable—I barely notice I’m wearing it, even overnight. What really stands out is how much insight it gives me into my body. The temperature tracking is especially cool—it helps me stay more aware of subtle changes I wouldn’t normally notice. On top of that, it tracks sleep, activity, and recovery in a way that actually feels useful, not overwhelming. The data is easy to understand and has helped me make small but meaningful changes to my daily routine. Whether it’s improving my sleep habits or just being more mindful of my activity levels, it feels like I have a better handle on my overall health. If you’re into wearable tech and want something discreet but powerful, I’d definitely recommend giving the Ultrahuman Air Ring a try. It’s one of those gadgets that quietly becomes part of your daily life—and you miss it when it’s not there.

Great ring: comfy accurate, and battery lasts days!

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 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.

After having the ring for over a month I have noticed that the battery life is not the best. I usually have to charge it every 2/3 days which is very annoying. However I do love the sleep aspect of the ring and feel that it is very accurate.

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.

So far love this ring and all the information it provides. Super comfortable and I hardly notice I am wearing it.

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

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 love this ring so much! It’s become an everyday item for me

Very good quality and fast shipping. Light and elegant design of the ring.

[Employee of bestbuy] 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.

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!

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

----- 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
