[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.

Took a couple tries to get the right ring size. I like all of the things it shows, sleep, steps, stress, cycle tracking and heart rate. Some days I don’t feel the sleep is as accurate, but maybe I’m a worse sleeper than I thought! Overall I like it. The app is easy to use.

[This review was collected as part of a promotion.] I got this ring for Mother’s Day and I love it. My only gripe is this is my second ring because my first one wouldn’t connect anymore and there have been a few times where I’m in workout mode my ring doesn’t register my heart rate. Overall I do love all the data the ring provides.

[This review was collected as part of a promotion.] Overall, I'm very happy with my Ultrahuman Ring AIR. The tracking features are great, the battery life is good, and the app is very user-friendly. My only complaint relates to the fading of the ring over time. I have had my ring for just under 1 year and it has gone from gold to mostly silver due to fading.

[This review was collected as part of a promotion.] I bought this ring two months ago and have been using is consistently - it had not disappointed! Really cool features and easy to use app interface, definitely the best health tracking ring you can find out there. Some measures do not feel completely accurate (sleep is sometimes a bit off, as well as movement is undercounted) but overall, compared to what most other fitness trackers offer, this is really good. I have tried various fitness trackers over the years, mostly watches, and the ring is much more convenient, highly recommend.

[This review was collected as part of a promotion.] Love the features and that everything I’ve wanted has been free with no additional subscription needed. If I followed the sleep tips better I know I would feel better but sometimes I ignore it. I only gave it a 4 because of the gold ring. I expect some scratches and stuff but I’ve only had this since January (24) and it is so scratched and beat up it looks super cheap now. I wish I had gotten the matte grey.

[This review was collected as part of a promotion.] I’ve had my ring for a few months now and I’m really happy with it. The battery lasts a long time on chill mode. I love checking my sleep each morning and all the stats throughout the day. It’s hardly scratched and is super shiny still.

[This review was collected as part of a promotion.] Former Oura user and Whoop user and I have to say the Ultrahuman is my favorite. It's got more features, it's more comfortable to wear, it's fast to update, AND there's no subscription. I'm super happy with it so far.
