[This review was collected as part of a promotion.] I purchased this ring almost 5 months ago, and could not recommend it more! The app is easy to navigate and has all of your data laid out in an easily-digestible format. I have worn this ring in the pool and during workouts and it had withstood all climates and activities. I use it during Hotworx and Corepower classes and it does not bother me when I use weights.

[This review was collected as part of a promotion.] I bought my ring about 3 months ago to replace my Apple Watch (which dies very fast). Having the Ultrahuman ring is amazing because I can charge it during the day and sleep with it on to track my sleep. I recommend this ring to every person I meet. It is comfortable, accurate, and has so many amazing features!

I bought this in March I believe, and I really enjoyed it at first, but once I got an idea of what my results were going to be, I ended up not checking them any more. I don’t find the battery lasts that long, maybe a day and half to two days. I do get compliments on the way it looks, but as for a smart ring, I tend to lean more towards using my smart watch.

After using the Ultrahuman Ring for the past month, I’ve found it to be an excellent tool for optimizing both sleep and physical performance. The sleep tracking has provided valuable insights that have genuinely improved my rest quality. I’ve also appreciated the detailed workout and recovery data, which has helped me tailor my training more effectively. One standout feature is the caffeine window—it’s been incredibly useful in managing my intake and supporting better sleep. Overall, a thoughtful and well-designed product for anyone looking to improve their health metrics.

[This review was collected as part of a promotion.] At first the battery life was a bit dissapointing. Latest update made it really great. I feel like it's continous developing which I love. I had problems with two rings in a row, but got replacement and good support. The third ring now works great.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring AIR for a few weeks now, and I’m genuinely impressed by how seamlessly it fits into my daily routine. It’s incredibly lightweight — I often forget I’m even wearing it — yet it delivers deep insights into my sleep, recovery, and metabolic health with impressive accuracy. What stands out most is the attention to detail in both the hardware and the app — the data is not only detailed but also easy to understand and act on. I’ve used other fitness trackers before, but this one feels far more focused and refined. The app’s nudges and insights are personalized without being overwhelming, and it’s been a real eye-opener in improving my sleep patterns and recovery habits. Overall, it’s a premium product that’s clearly built with purpose. Highly recommended for anyone serious about optimizing their health and performance!

[This review was collected as part of a promotion.] Since becoming a first-time mom, managing my sleep has been a challenge — but the Ultrahuman Ring has made a huge difference. It’s so light and comfortable I forget I’m wearing it, and it gives me super useful insights to help prioritize rest without any extra effort.

[This review was collected as part of a promotion.] Best investment in my health in a long time. It's been incredible to have instant access to so much useful data in such a simple and easy to understand way. I only need to glance and I have so much information throughout the day. I originally got this purely for the sleep tracking but I have quickly found every aspect of the ring useful - the insights I'm getting are so worth it. It's also such a plus not having to pay a monthly subscription for the app.

[This review was collected as part of a promotion.] The Ultrahuman ring is a great alternative to the Oura ring. The app is very functional and easy to use breaking information down, unlike the Oura ring. The ring offers important insights into your health allowing you to make subtle changes to your lifestyle for the better. Love the ring and would recommend it to anyone in the market for one.
