[This review was collected as part of a promotion.] Bought this mainly for sleep tracking as hate Apple Watch in bed. The ring is light reliable and get 5-6 battery without worrying about it. On top of that I really like the app and the insight it provides on top of sleep tracking, If your on the fence about purchasing I would go ahead and do it

[This review was collected as part of a promotion.] I have purchased my ring ca. 3 months ago and using it ever since. What I like: - sleep tracking - caffeine window - workout tracking - workout tracking - new parent function :) - the UI has a nice appeal - no subscription What I would change: - bad connectivity with ring-phone - long updating times between ring and phone (updated app, reseted phone, meanwhile changed to new phone) - every time ring update is available I have to reset the whole ring since it remains stuck updating The overall appeal of the ring is positive with some throwbacks, mostly SW related. If new ring will be available on the market, I highly consider upgrading :)

[This review was collected as part of a promotion.] I bought the Ultrahuman Air ring a while back and it has been one of the most used device to track my health. At the moment of the purchase, I was constantly having troubles with my sleep and it has been really useful to be able to see the stages of each night. I also really loved the other features, especially the dynamic recovery and the advices it comes with. The only downside I found is that there are differences between my watch and ring inthe movement scores, but nothing too massive. The battery life had change over time, now it is shorter, but I also know that I had it for quite some time. I also love how there are all sort of updates, both in the app and the firmware and how you can see that the developers really care about their products. I would really recommend it

[This review was collected as part of a promotion.] I am very pleased with this ring! I tell everyone I get a chance to about it. The ring is sleek and comfortable on my finger. I have been wearing it for about 5 months and I don’t notice any chips or cracks at all. I purchased it as the most cost effective way to track my sleep, steps, and menstrual cycle. I have been tracking my cycle for a few years but this has taken it to the next level and given me more accuracy. The battery life is really good, I only charge my ring every 4 or 5 days. Definitely satisfied with my purchase!!!

[This review was collected as part of a promotion.] I've been using the ring for almost a year, and am mostly happy with it. It packs loads of advances metrics in the app, something other vendors charge a subscription fee for. The only drawback is that it sometimes (<weekly) fails to sync and I loose out on a day or so of numbers. Charging it, even if it has a lot of battery left, will make it sync again so fairly easy fix.

[This review was collected as part of a promotion.] I have a health issue known as Hashimoto's so my health tends to be a bit all over the place. This has been a game changer for me because I am able to gather metrics on what's going wrong with my body due to a specific lifestyle and it has been insanely motivational for me to get things back to normalcy and live a better life. I am also eager to meet my doctor and share the data from the Ultrahuman Ring Air and see if it helps him in recommending further changes.

[This review was collected as part of a promotion.] This ring has truly helped me understand my health to the fullest. I originally purchased to track my sleep, and it has helped me get my health on track by understanding my heart rate, HRV, and stress. I've already set personal records by exercising more and lowering my stress levels and heart rate! The only reason why I took off one star is because the smart alarm in the app is a bit buggy. There have been multiple times the alarm didn't go off even though it was set for the correct date/time.

[This review was collected as part of a promotion.] Initially was great very quickly went down hill. Has struggled with connectivity and battery life, dies in a day and a half maybe two days sometimes on chill mode. It constantly wouldn’t track my sleep data and would show 2-3 hours of a 8 hour sleep. I have already requested a refund for the clearly faulty product. If you can fix these issues I’d be interested in continuing to use Ultrahuman as I do believe the product and what you are towing to achieve

[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 really like all the things this ring measures. It's very interesting to watch how what I do in the day affects my sleep that night, from the HR drop to sleep cycles and the length of each phase. Very helpful and interesting, definitely don't regret buying.
