[This review was collected as part of a promotion.] So glad I decided to invest in an Ultrahuman! I originally invested in it for its ability to seamlessly track my sleep without having to wear an uncomfortable watch to bed (that would also have to be charged at some point in a 24 hour window. Since then, I can honestly say that my ring has helped me recognize and transform habits from sleep to Vitamin D exposure to caffeine intake to morning rituals. Excited to see how Ultrahuman keeps evolving!

[This review was collected as part of a promotion.] Received as a gift, purchased the extended warranty and cannot use warranty because I do not have a receipt or purchase info. Very disappointing because I was loving my ring, but now must abandon my ring (note: support will not authorize replacement without purchase info) plus dispute the money I paid for extended warranty. Spent hours on chat trying to resolve this, and I'm so aggravated by the process its impossible to leave a positive review.

[This review was collected as part of a promotion.] Overall, I am really enjoying my Ring AIR. It’s pretty accurate and I enjoy all of the features and ‘power plugs’ that are available. I love that you don’t have to pay a monthly fee for the app, that’s why I chose this option instead of the Oura. I have had some problems with the ring tracking and syncing both my sleep and activity at times, which is a little frustrating. I’ve contacted support through the app and each time they’ve been helpful! I’m happy with my purchase and would recommend!

[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.

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 got this about 4 months ago and have loved getting all of the feedback that this ring tracks. It is very insightful and helpful in knowing more about my body and what it responds well to and what it does not. The sleep feature is my favorite by far.

[This review was collected as part of a promotion.] I have been using the ring for about a year now and I am very satisfied. I track my sleep cycles every day, I follow the caffeine window, I use it a lot when exercising. All the results are very clearly interpreted, I use several powerplugs. I would definitely buy it again.

[This review was collected as part of a promotion.] I have been using the Ultrahuman Ring for a few months and I’m very happy with it. I especially like the sleep and stress insights, which help me understand my habits better. The app is intuitive but the only thing I feel is missing is a bit more guidance on how to interpret the data and clear tips on how to improve. Still, I highly recommend it!

Being able to see what habits garner positive results has helped me be consistent with the healthier changes I have made to my lifestyle. This product has seamlessly fit its way into my health journey.
