[This review was collected as part of a promotion.] I love i'm able to track my sleep, stress and recovery. Its so light i barely felt its there. It kinda replaces my smartwatch. I said kinda because there is still some features that i hope it has but it doesnt. Example the find my phone features, and i do hope that it has a better ability of recognizing when i'm doing a workout.

[This review was collected as part of a promotion.] The ring is truly remarkable. The app provides comprehensive information about your sleep, stress levels, dynamic recovery, and even your cardio age. It has undoubtedly empowered me to delve deeper into understanding my body’s functions.

[This review was collected as part of a promotion.] I’ve been using the ring for a couple of months and I’m thankful that it has made me conscious of my overall health. Now, I’ve become conscious of my sleep patterns and also the times I get stressed and their triggers.

I bought the ring several months ago, so here is my honest review. As a mom of 3 I’m always on the go, survive on coffee and barely get any sleep. The Ultrahuman ring reminds to cut down coffee at certain time of the day and records how many hours of good sleep I got and how many hours I owe myself lol And I really love that! It makes me feel more conscious about managing my coffee intake and sleep habits. Also records my stress levels which it’s so helpful to me because it’s I find myself searching for ways to decrease stress. It has other amazing features, but those are the main ones I use everyday. I took one star off because the battery usually last me 3 days and I wish it lasted longer than that.

I bought this a while back, and at first, it worked well. However, I realized the battery doesn't actually last the whole week, just 3-4 days maximum, and I charge it overnight. The ring also randomly disconnects or says there is not enough data to give me my sleep records, for example, which is weird when I know for a fact I slept 6 hours.

[This review was collected as part of a promotion.] I’ve had my ring for about 6 months now, and it’s truly been a game changer. Gaining insight into how my body functions—especially when it comes to sleep—has been incredibly valuable. My main reason for getting it was to improve my sleep, and the data has helped me make meaningful adjustments to my sleep hygiene and nightly routine.

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.] 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 love my ring!! It’s so light and comfortable to wear. For the most part it provides very informative and accurate insights. One thing I’ve noticed is the step count is very off from my Apple Watch. I wear both realistically so I’m ok with that since it’s more accurate in other areas. Overall I love my ring and has made a huge difference in my sleeping habits! Definitely recommend the purchase.

[This review was collected as part of a promotion.] Earlier I was using Apple Watch which was cumbersome to wear at all time especially during sleep and charging daily was an issue .Since I have started using Ultrahuman I am happily tracking my daily activities especially sleep and calories with a good battery life.the best feature is the alarm clock which will wake you up according to your REM sleep which will make you feel fresh on getting up. It correctly calculated my sleep deficits,sun exposure,heart rate variability and dynamic recovery .. all of which is required to be monitored to stay fit in this stress driven world .Ultrahuman is amazing
