[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring consistently, and it’s genuinely changed how I approach both training and recovery. The insights are spot on, being able to see how my sleep quality aligns with my workout performance has helped me tweak my gym routine in a way that actually sticks. I now train smarter, not just harder. Days I used to push through fatigue, I now recognise as signals to recover, and the results have been visible in both strength gains and overall energy. Sleep tracking has been especially helpful; knowing when I’ve rested well (and when I haven’t) has brought a level of awareness I didn’t expect from a wearable. I have it in Gold - looks pretty, easy to wear all day, and blends right into my routine. Would highly recommend if you’re serious about optimising both training and recovery.

[This review was collected as part of a promotion.] I bought this ring for sleep tracking and it does this really well, much better than Apple Watch. so I don't need to wear the watch at night any more! it is starting to give me actionable comments after eg a bad nights sleep, but it is early days to know how this will impact my sleep habits etc. only 4 stars as after a number of weeks it disconnected from my phone and it took a while to sort out what was wrong. I contacted support and I had to do a battery re-set which involved letting battery completely die, which took about 4 days. I then re-charged it for a few hours and it connected back too my phone easily. It will now take a few days to see if I am back on track with data again.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring AIR for the past few weeks, and I can confidently say it's one of the most impressive health wearables I’ve ever tried. 💤 Sleep Tracking: Unmatched Accuracy The sleep insights are incredibly detailed — not just light/deep/REM stages, but also sleep efficiency, HRV, resting heart rate, and temperature deviation. I finally understood why I felt tired some mornings even after 8 hours of sleep. ❤️ HRV & Recovery Monitoring The Ring gives me daily Recovery Scores, factoring in my HRV, temperature, and sleep quality. This has helped me optimize my workouts, knowing when to push hard and when to rest. I’ve never felt more in tune with my body. 🔥 Movement & Metabolic Scores Ultrahuman doesn’t just track steps — it gives a holistic view of how much I’m moving and how it impacts my metabolism. Combined with smart nudges, I’ve naturally improved my daily habits without feeling pressured. 📱 Beautiful, Intuitive App The Ultrahuman app is beautifully designed, easy to navigate, and filled with actionable insights. I’ve used other platforms like Oura and Whoop, but Ultrahuman feels more modern, practical, and motivating. 🪶 Comfort & Battery The Ring AIR is super light, I forget I’m wearing it — even when sleeping or working out. Battery life easily lasts 4-5 days, and charging is fast and hassle-free. Ultrahuman Ring isn’t just another fitness tracker. It’s a real-time feedback loop for your body, health, and lifestyle. Whether you're an athlete, a biohacker, or just someone who wants to optimize energy, sleep, and stress, this ring is a no-brainer. Highly recommended. 10/10.

The first ring lost charge within 1/2 a day. The replacement ring has functioned alright. The data acquired seems reasonable, but changing to accommodate the suggestions, less so! Life changes day-by-day and hour-by-hour...It is not always easy to be in the green all the time.

[This review was collected as part of a promotion.] While the ring itself is good, I’m not happy with the app experience. The information that’s presented is very confusing and I am unable to understand some of the details it shows like phase advance, etc. The accuracy of its detection of my activity is very poor. The app sometimes shows activity detected and asks me if I want to add it and most of the times it doesn’t. The tagging is very bad, I can’t find the tags I want. If I add a custom tag, it won’t get stored so that I can reuse it. The type of workouts are not comprehensive. App leaves a lot to be desired with features, user experience and functionality.

[This review was collected as part of a promotion.] I love my ring. It took a little to get adjusted to it and now I feel naked if I leave the house without it. The tracking is interesting and a lot more accurate than my apple watch of Fitbit ever was. I love that I am getting more in tune with how my body reacts to certain things like sleep deprivation, eating later meals and proper recovery from stress, stimulants, working out and lack of sleep.

[This review was collected as part of a promotion.] I bought this ring May 2025 and had the ring for about 3 months until the ring stopped holding battery. The battery would last less than 24 hours in the battery saving mode when it was supposed to last 4-6 days. When I contacted support about it they were very helpful and eventually sent me a completely new ring - hopefully this one lasts. Besides that I have really enjoyed the ring especially the circadian phase tracking. I use the ring as contraceptive so I hope they come out with more features to support that tracking!

[This review was collected as part of a promotion.] I purchased this ring to help track my sleep, fertility, and movement. I love the data available to me from body temp, to my sleep quality (which needs improvement!), and tracking my activity (especially the reminders to get up to stretch and/or move). The only downside is the battery life. I have it on the lowest battery setting (chill mode) and still feel like I need to charge it every other day. I love that purchasing the gold ring wasn’t a difference in cost (as compared to competitors) and that I don’t have to pay extra for cycle tracking!

[This review was collected as part of a promotion.] I love my Ultrahuman ring. Having insight into my sleep and recover has been eye opening. It has made me make changes in my sleep hygiene so that I get a better deep sleep and ultimately a better recovery. The reasons I didn’t give it a 5 are: the battery really only lasts 3-4 days, I am unable to wear it while I Olympic weight lift so I can’t track my workouts and it seems to be quite different on the step counter then my Apple Watch which I wear on the same hand. Besides that I think having it has made a very positive improvement in my overall health and I’m happy I bought it.

[This review was collected as part of a promotion.] I’ve had the Ultrahuman air ring for 8 months now and I love it! I’m not a huge jewellery person but it’s a super lightweight ring and I don’t even notice it on my finger anymore. I originally bought it mainly for the sleep tracking, but there are so many features which are all used for analysis and to provide rich insights into your health. Ultrahuman are also constantly updating the app and adding new features- at no extra cost, in comparison to other rings which have a monthly subscription. My only tiny drawback is that depending on the updates sometimes the charge runs out fairly quick (like 1.5 days).
