I love this ring- it has such in depth tracking, and I love all the power plugs. I like that it has more sleep analysis than my garmin watch

Great ring but battery problems

[This review was collected as part of a promotion.] I bought this ring May 2025 and had the ring for about 3 months until the ring stopped holding battery. The battery would last less than 24 hours in the battery saving mode when it was supposed to last 4-6 days. When I contacted support about it they were very helpful and eventually sent me a completely new ring - hopefully this one lasts. Besides that I have really enjoyed the ring especially the circadian phase tracking. I use the ring as contraceptive so I hope they come out with more features to support that tracking!

[This review was collected as part of a promotion.] I have had this ring for about 2 months and absolutely love it. It has all the tracking I wanted without the subscription and much cheaper than other rings on the market

[This review was collected as part of a promotion.] I bought the ultrahuman ring a little over four months ago, and was impressed with how well the ring has held up. I appreciate the insights it can provide, as well as the sturdiness of the ring.

Need to work on calories and steps accuracy
on September 3, 2025
Posted by: KaB1
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.

Accurate, Comfortable, and Sleek!

[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.
