[This review was collected as part of a promotion.] I bought this ring in april and I had a great first few months. I am now having problems with the battery of the ring and hard time connecting the ring to the app. I am in the process of troubleshooting with the app. So hopefully in the next two days the ring experience improves.

[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!

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.] The Ultrahuman Ring Air has completely changed the way I understand my body and health. One of the biggest benefits has been the clarity it provides around my energy levels—I can now pinpoint exactly why I’m feeling tired or off on a particular day, and the app highlights areas I can actively work on to improve. I was genuinely surprised to learn that my sleep quality wasn’t as good as I thought. The detailed sleep insights made me more mindful about my routine and helped me make small changes that have had a big impact. Comfort-wise, the ring is exceptional. It’s light, sleek, and feels like a natural extension of my body. I barely notice it, even while sleeping. I’ve also tested it in pretty rough conditions—during gym workouts, heavy weightlifting sessions, and outdoor runs—and it’s held up flawlessly. Extremely durable. Only downside: The app tends to consume a significant amount of battery in the background, even when the ring isn’t actively connected. I hope future updates address this issue. Overall, highly recommended if you're serious about understanding and improving your health.

[This review was collected as part of a promotion.] I love this so so much. The insights are incredible and eye opening. I love being able to track my monthly cycle and most times it's on 9/10 times! I love being able to correlate my sleep tracking with caffeine intake. I wish the battery lasted a little longer though but wow, this ring is incredible. Not having to pay for the app to get the basic features is already a one up.

[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.] This ring has motivated me into adopting healthy lifestyles and once you reach there, the rewards are very fulfilling. Loved the experience so far. I work offshore so not sure how this ring will play outside of internet connection for long periods but for now, this ring has performed pretty well so far.

[This review was collected as part of a promotion.] I bought this a few months ago and I love it so far. It's much less bulky than other workout/sleep/lifestyle smart trackers and I feel that the insights are helpful in detecting where I can improve my sleep and exercise habits.

[This review was collected as part of a promotion.] This ring has been great, I’ve really enjoyed the sleep tracking and it tends to pick up activity quite well even when I don’t go in and log a workout myself. I moved from an Apple Watch and much prefer the Ultrahuman ring

[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.
