[This review was collected as part of a promotion.] I've had this ring for almost 2 months and it has helped me better my sleep and shown me that I need to move my body more. Love the caffeine tracking feature and cycle tracking so far has been spot on even 2 months in.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman ring for a month and a half now and it’s really helped me improve my sleep and track my menstrual cycle but one feature I think that is really missing is a tracking feature similar to what an AirTag has because I have misplaced my ring a few times And find my ring sensor on the app is not helpful at all unless you are less than a meter or two away from the ring. If you have misplaced your ring in your friends house for example or in a restaurant the find my ring feature will not help you at all. I’d love for them to improve this feature or add some sort of tag to it so we can see it on find my friends.

[This review was collected as part of a promotion.] I am thrilled with my Ultrahuman Air ring. I purchased it and a leading competitor to do a side by side review. After just 2 weeks, I returned the other ring - the Ultrahuman was just so much better. The Ultrahuman app is amazing. Almost immediately I started seeing improvements in my sleep, health and energy level. Both my Ultrahuman app and my Apple Health app showed significant improvement in many areas (HRV, deep sleep, amount of sleep, Vo2, resting heart rate, etc.) in just a few weeks. I did a lot of research before buying. In the past several people have had problems with their ring not recording data. I have not had any problems. But one person said that when you are picking a size it's best to get a ring that is too tight to take off in the morning without using water. I did that and my ring stays in place during the night. If the ring is too loose it will twist around and not be able to record your info. Also, try to pick a size of ring that you can move to other fingers if you lose or gain weight. Finally, the ring is NOT as good in measuring workouts and your steps as the Apple watch. But I have a watch for that. From personal experience the ring is MUCH better at tracking sleep. It often shows more deep sleep than my watch. Also, it tracks the REM and other stages more accurately. Often I wake up suddenly during a dream. The ring shows that I have gone directly from REM to awake. The watch does not show that.

[This review was collected as part of a promotion.] I have had the ring for a few months now. Overall I have had a great experience. I with there was more in depth information for mental cycle tracking. Also more capabilities for logging information about the days activities that could affect different statistics.

[This review was collected as part of a promotion.] Have had this ring for a little over 8 months. overall my experience with the ring has been good, there are a few features that I feel are missing from the app. Also the social jet lag feature has never worked for me. I think the app could use some enhancement for ease of use

[This review was collected as part of a promotion.] I’ve been using this product for over four months and it has exceeded my expectations. The quality is outstanding, performance is consistent, and it’s incredibly easy to use. Definitely worth the investment, and I’ve already recommended it to friends. Great purchase that delivers exactly what it promises.

[This review was collected as part of a promotion.] I was gifted this by my bf for our anniversary and I love it. I was a bit worried about the app interface but it is actually really easy to use. Wearing this ring has helped me greatly with my sleep schedule and overall wellness habits. One thing it is not super great for is its real-life heart rate check.

[This review was collected as part of a promotion.] Absolutely love the Ultrahuman Ring. It’s sleek, comfortable, and works like a charm. Tracks sleep, recovery, and activity accurately, and the insights are genuinely useful. Battery life is solid too. Overall, it’s become a part of my daily routine and I can’t imagine going without it now.

The ring works well. I tracked the results against my Garmin watch and the readings were very similar. The app is a bit messy, it could use some streamlining or function to customize for personal focus and goals. I do like being away from a bulky watch.

[This review was collected as part of a promotion.] I brought the Ultrahuman ring AIR back in March. It’s been really insightful knowing the internals of my health, how my sleep can impact my recovery and mood throughout the day. The caffeine window has been really helpful. The menstrual cycle tracking has helped me understand my body more. I would totally recommend buying, I have influenced many of my friends to get it.
