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.] The ring doesn’t hold charge for more than a day or two. Wish the app did more.

Great insights, some features could be better

[This review was collected as part of a promotion.] Been using the Ultrahuman Ring Air for about 4 months. Overall experience is very good, I really enjoy all the detailed info the device collects. Far more detailed, accurate and helpful than any other device like smartwatches. Battery could be better but it’s not terrible. Some features in the app require an app to be running in the background. Smart alarm in my case sometimes isn’t turned on due to app not running in the background. And the majority of time it only triggers with a fallback timing.

Comfortable & Reliable

[This review was collected as part of a promotion.] I purchased my Ring AIR back in March and I’m very happy with the results. It has made me more aware of my sleep patterns, sunlight exposure and overall health. It’s very important for me to keep track of these items because if my sleep hours are low then it can affect me during my daily routine. The ring is comfortable and no issues with wearing it while I sleep. It does charge pretty fast which is convenient. Overall, happy with my purchase!

[This review was collected as part of a promotion.] I bought this like 3 months ago and I love all the data it tells me. My sleep scores are definitely impacted by things I do and so now I avoid certain things at the end of the day.

[This review was collected as part of a promotion.] I have had this ring for about 5 months and I absolutely love it. I use the sleep insights and tracking my menstrual cycle. I have recommended to a few friends already.

Good ring, so-so battery
on July 9, 2025

[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.
No, I would not recommend this to a friend.
