[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’ve been using the Ultrahuman Ring AIR for a few months now, and I’m really impressed with how accurate and insightful the data is. It tracks my sleep, recovery, and activity seamlessly without ever feeling bulky. The design is sleek and comfortable—I hardly notice I’m wearing it. The app is easy to use and gives me clear, actionable insights that actually help me improve my daily routines. Battery life is great too, and it charges quickly. Overall, this ring has exceeded my expectations and has become an essential part of my wellness journey.

[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.

[This review was collected as part of a promotion.] The ring has set me on a journey to better understand how sleep affects my health. I’ve received insights I did not know about. I have been able to see how certain behaviors, like late meals, stress, or room temperature affect my sleep. The ring is also very comfortable. I hardly feel it on. The battery life is very good. I charge it about once a week. I bought the silver color. Been wearing it for about a month and don’t have any scratches on it. Overall, I’d recommend this to anyone who wants to improve their health. The key is to stay disciplined and consistent with insights and tips.

[This review was collected as part of a promotion.] I bought this ring at the start of the year and it has been a gamer changer! So helpful for me to keep track of my zones during workouts, monitor my sleep and adjust my routine to maximise my readiness for the day

[This review was collected as part of a promotion.] I love the product data and my husband and I have been using it together. However, my purchased my ring and it have connection issues and it never connected properly. ULTRAHUMAN were great at replacing the ring however, after only a month or so of using it, my ring has stopped connecting altogether. It works great for my husband so I’m frustrated it’s happening. However I hope it will get resolved as the app is great!

Sleep features are good but the activity tracking and calorie burn estimates are not good. The calorie burn on your app barely covers my baseline metabolism and my activity burns almost twice that. Also, I thought the ring would be able to tell me when I’m possibly sick and it has missed that twice.

[This review was collected as part of a promotion.] Overall, really happy with the superhuman ring. I like all of the things that tracks. If I was being critical, I think that the walking step count can be inaccurate at times especially when driving in the car with bumps it will still record steps so by the end of a very long drive you can have over 10,000 steps recorded Other than that’s great

[This review was collected as part of a promotion.] Bought the ring about six months ago, it’s been great as I’ve never really liked the watches or bracelets. Really like how it monitors stress and sleep and movement, looking forward to more powerplugs to add on in the future. The only thing is the ring keeps saying my body temp is too high but I actually feel cold most of the time so not sure what’s going on there.

[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.
