[This review was collected as part of a promotion.] I bought this ring 2 months ago and it has given me so much knowledge into my body and it is so lightweight on the finger . The only thing is the battery life does not last as long as advertised. For me it’s about 4 days max, which I don’t mind.

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.] Using it for 8 months now and I am very happy with it! I've been using it for 8 months and I'm really pleased. It has helped me understand how I sleep and what I can do to improve it. As a result, I'm sleeping much better now. I also really enjoy using it while exercising, as it gives me clear insights into my performance and helps me track my progress. Highly recommended if you want to gain more control over your sleep and overall health!

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Air Ring for a while now, and it has quickly become one of my favorite health and fitness gadgets. The first thing that impressed me is how lightweight and comfortable it feels. I often forget I’m even wearing it, which is perfect for 24/7 tracking. The ring tracks key health metrics like sleep, heart rate, and activity levels with impressive accuracy. I especially like the sleep insights—it doesn’t just tell me how long I slept, but also provides recovery scores and actionable suggestions to improve rest. The activity tracking is equally useful, helping me understand my daily movement and energy expenditure without the bulk of a smartwatch. The companion app is sleek and intuitive, with clear visualizations and trends that make the data easy to digest. I also appreciate the nudges and insights it gives for improving recovery and performance. Battery life is solid; I can go several days without charging, which is a huge plus for continuous tracking. If I had to point out one minor area for improvement, it would be expanding the integrations with more third-party health apps. But overall, the Ultrahuman Air Ring is a fantastic investment for anyone looking to monitor and optimize their health without wearing a traditional fitness watch.

[This review was collected as part of a promotion.] For a long time I was looking for something that would measure everything like a smartwatch. And I found something way better, and comfortable in use. Very user- friendly app and very accurate measurements/predictions.

[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.

[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 bought my ring back in March and I have loved it ever since! It keeps track of all of my sleep, including my naps! I love to check my stats as soon as I wake up and throughout my day. It keeps track of when I should and shouldn't have caffeine as well! I like that it keeps up with my ultrahuman age and my heart and brain levels. It makes me feel way better about myself and my lifestyle, knowing that I have an app and ring to keep track of all my information and see what is improving and what is not! This ring is the bomb diggity! I highly recommend it, it's worth the money!!

[This review was collected as part of a promotion.] I bought this ring to track sleep and motivate me to improve my sleeping habits. It has helped tremendously. As a bonus, I love the caffeine window and it tracks my stress level which always amazes me how accurate it is to what is going on.

[This review was collected as part of a promotion.] I bought the ultra human ring about 2 months ago and so far I’m loving it . I had an Apple Watch previously but I really like that the ring focuses more on overall health insights as opposed to exercise. The sleep score and cycle tracking are my favorites and I enjoy seeing how my sleep ties to my overall health.
