[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring AIR for a few weeks now, and the difference in sleep quality and recovery is night and day. The real-time biomarker insights (especially HRV and skin temperature) gave me more control over my routine and helped me make smarter lifestyle choices. It’s not just a tracker - it’s a personal performance optimizer. Looking forward to more firmware upgrades and continued improvements. Great product, strong ecosystem.

[This review was collected as part of a promotion.] I've had my Ultrahuman Ring Air for over a year, prob closer to two years and it's been great!!! I mean really great!!! Things I love..... The data is super helpful and really easy to interpret and make use of, thanks to how its displayed in the app. Personally I really like the sleep, recovery and movement index scores. Until recently it had a really reasonable battery life and lasted well with short charges when taking a shower so I could wear the ring while I sleep. However recently...... the battery hasn't been fully charging despite being left on the charger for hours it only reaches a max of 80% charge, so I'm constantly getting low battery warnings which is really disappointing. Also I wish I had got this ring in a bigger size for my index finger and in gold (however when I bought it these rings were really hard to get in the uk and the retailer didn't have the gold only the dark grey colour and only in this size so I settled & I wish I hadn't) I like the ring so much that I have been contemplating getting another however the recent charging issues have me reluctant to invest when I want a product that will continue to perform well for the long term. I hope the issues I've experienced are a one off and not reflective of all products in this range as other than this I cannot recommend the Ultrahuman Ring Air enough for those who are serious about improving their health based on real time data and easily interpretable metrix.

[This review was collected as part of a promotion.] I used to think I was sleeping fine, but I couldn’t figure out why I still felt off some mornings. This ring helps me understand my sleep. It reflects how I feel in clear useful data. I’ve had it for almost a year now, and it’s still a part of my everyday life.

[This review was collected as part of a promotion.] I’m really satisfied with my ring, your communication, and the support. What I like most about Ultrahuman is that you’re constantly evolving and iterating. You’ve introduced some very cool features so far. I was also pleasantly surprised by your support — I received an automated email notification that my charger was overheating, and you proactively sent me a new one. I’ve never experienced such proactive service from any other product. Kudos to you all! If I had to pinpoint one area for improvement, it would be the accuracy of your algorithm. I saw a review on YouTube by a scientific reviewer, and I was a bit disappointed with the results. But I’m hopeful that future updates will improve it. Keep going!

[This review was collected as part of a promotion.] I love my Ultrahuman Ring Air. It provides me with great insight on a lot of health data. It also tells me how to improve my scores when they are not the best. One of my favorite things about the ring is my sleep score and how that affects my caffeine window.

[This review was collected as part of a promotion.] I love the feeling of knowing how my body is functioning and how it may impact my day. The ring helps me understand when I may need to be more active, get to sleep earlier, and also when best to have caffeine for optimal productivity! I love it!

[This review was collected as part of a promotion.] I bought this a few months ago and I really love it. So far it’s been very accurate and I’ve found a lot of the metrics super beneficial in comparison to my watch that tracks similar things. I’d definitely recommend it to anyone.

[This review was collected as part of a promotion.] I have been using my ultra human ring for almost a year by now and for me it’s has been amazing because I have a chronic illness characterized by inflammatory crisis, my ring has been son accurate that by now I know when a crisis is coming because the ring notify me about increase in my temperature and inmune overload, this helps me prepare better for those next days.

[This review was collected as part of a promotion.] I absolutely love the ring it’s helped me improve my sleeping pattern and help with my overall focus on my health. My only issue is the charging dock, I don’t know why when I put it on the dock I have to keep moving it to keep it charging. Don’t know if I’m doing something wrong or what.

[This review was collected as part of a promotion.] I've had the ring since February 2024 and have loved it since day one. My main goal was to track and improve my sleep — and I’ve managed to do both. The missing star is due to occasional issues with the app not syncing properly with my fitness tracker (Strava). I usually don’t wear any ring during workouts (rowing, training, etc.), which sometimes causes the ring to misinterpret the lack of activity.
