Good ring, so-so battery

[This review was collected as part of a promotion.] I am happy with the insights this ring has given me in regards to sleep quality/timing, stress levels. It is light on my finger and most of the time I hardly notice it is there. I did have an issue with my first ring but was quickly sent a replacement. Unfortunately I have had relatively consistent issues with battery life even after troubleshooting in the app multiple times and using Chill mode (less battery utilization). For example, I will start the night with near full charge and be down to <30% by awaking in the AM. I wonder if some of the battery issues are firmware related as I had relatively good life for several months but then had an acute decrease in battery life in the past 1-2 months.

Still Evolving!

[This review was collected as part of a promotion.] With this single device, you can accurately monitor all the essential health metrics typically tracked by a smartwatch—such as calories burned, sleep analysis, blood oxygen levels, heart rate, and skin temperature. What sets the UltraHuman Ring Air apart is its ability to go one step further by offering personalized advice and tips to help you improve your daily lifestyle habits.
I started using this ring around March, and since then, its features have been continuously updated. New functions like “Brain Age” and “Pulse Age” have been added. It’s a smart ring that continues to evolve every day.
スマートウォッチでわかること(カロリー、睡眠分析、血中酸素濃度、心拍数、皮膚温度)など基本的なことは、これ1つで正確にデータを見ることができます。 UltraHuman Ring Airはさらに一歩踏み込み、日常の生活習慣を見直すためのアドバイスやTIPSを提案してくれる点が素晴らしいです。
このリングを使い始めたのは3月頃からですが、日々機能がアップデートされており「脳年齢」「脈拍年齢」など新たな機能が追加。日々進化し続けるスマートリングです。

[This review was collected as part of a promotion.] I love my Ultrahuman Ring Air. It provides me with great insight on a lot of health data. It also tells me how to improve my scores when they are not the best. One of my favorite things about the ring is my sleep score and how that affects my caffeine window.

Great quality and accessibility!

[This review was collected as part of a promotion.] I purchased this ring almost 5 months ago, and could not recommend it more! The app is easy to navigate and has all of your data laid out in an easily-digestible format. I have worn this ring in the pool and during workouts and it had withstood all climates and activities. I use it during Hotworx and Corepower classes and it does not bother me when I use weights.

From Unaware to In Control—All Thanks to This Ring

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring AIR for the past few weeks, and it’s really shifted how I look at recovery and staying focused. I’ve started noticing patterns in how I sleep and move through the day, and it’s helped me make a few small changes that actually stick. The recovery score, in particular, makes a lot of sense to me—I find myself checking it before I even start the day. Kind of wild how something this small can be so useful.

[This review was collected as part of a promotion.] At first the battery life was a bit dissapointing. Latest update made it really great. I feel like it's continous developing which I love. I had problems with two rings in a row, but got replacement and good support. The third ring now works great.

Faulty product from start to finish.

[This review was collected as part of a promotion.] I bought the ring first in May, and it stopped working in a week's time. The second time, I received the ring from Ultrahuman as a replacement for the faulty ring; this time the ring stopped functioning in 20 days' time. This has to be one of the worst products that I have bought. Once the ring runs out of battery, the ring will not turn back on.
No, I would not recommend this to a friend.
