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 love how much it tracks especially since they keep adding more power plugs. The battery life could be better though but otherwise overall a good ring

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.

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。

Ultrahuman Ring Air is very helpful!

[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.
