[This review was collected as part of a promotion.] I bought my Ultrahuman Ring AIR in March and have loved wearing it throughout this past Summer. I love waking up to see my statistics and then checking throughout the day to see how I can improve. I use my ring mostly for step count and all things heart, sleep, and cardio health. The ring is also very stylish and I get complements and questions frequently about its use. It brings me a real sense of peace to have these features and truly be in touch with my health on the daily!

[This review was collected as part of a promotion.] Really happy with the ring, it pushed me to walk and sleep, and it radically improved my life. All the stats have nice widgets, finally I can track my coffee intake (previously it was so chaotic). I feel a loooooot better. Waiting for the weight loss feature. My wife gotta Oura, so we can compare. And I'm super happy I picked Ultrahuman. Everything goes really good so far. I had a minor scratch though, probably from a cat. But other than that, I'd definitely buy another one, when this one is dead.

[This review was collected as part of a promotion.] Works great. Let's me know when to go to sleep and when to drink coffee😏 Keeps track of steps walked. Let's you know how long you were in each stage of sleep. Deep, rem, light. Provides all health stats and tells you how to improve them.

[This review was collected as part of a promotion.] I really enjoy the Ultrahuman ring AIR! The in depth data results allows me to plan my health and life intentionally, whether I need to take a rest day or exercise harder, go to bed earlier or know what time to wake up etc. the information is amazing!

[This review was collected as part of a promotion.] I was sleeping 7–8 hours most nights, but waking up feeling like I hadn’t slept at all. I’d scroll through sleep tips online, try magnesium, meditation, no screens before bed—you name it. Nothing really stuck, because I didn’t know what was actually going wrong. This ring changed that. It didn’t magically fix my sleep overnight, but it finally gave me a way to see what’s happening while I’m asleep. Turns out I wasn’t getting enough deep sleep, and my recovery scores were way off after high-stress days, even if I hadn’t worked out. The HRV data, resting heart rate, even skin temperature started to paint a fuller picture of what my body was going through. I also started noticing how my sleep improved when I ate earlier, skipped alcohol, or took a proper wind-down routine seriously. Before, it all felt like guessing. Now it feels like learning. The ring itself is great—super light, looks good, and I barely feel it at night, which is huge. I didn’t want another thing buzzing on my wrist. Honestly, I bought this ring because I was tired of being tired lol. But it makes a huge difference in my life.

[This review was collected as part of a promotion.] I’ve been wearing the Ultrahuman Ring for over a month now, and honestly, it’s been a bit of a wake-up call - in the best way. I’ve become way more vigilant about my overall health. Not in an obsessive way, but in a way that feels informed. Like - I’m not just guessing if I recovered well after a long day or a workout, I know. And that’s empowering. I’ve genuinely started caring about winding down properly, just so I can hit those sleep goals - and I feel the difference the next day. It’s not just a ring- it’s a personalized trainer I didn’t know I needed.

[This review was collected as part of a promotion.] This has been soooo helpful especially with sleep and now I know why I am so tired! It has also helped me with my activity level and has made me increase my steps - daily. The only thing that I have an issue with is sometimes when I have an activity running, for example I’m out running. It will randomly just close out and I have to start over again when I’m already midway through my workout.

[This review was collected as part of a promotion.] This ring has helped me better understand myself. I’ve been trying to improve my sleep habits and this tool has kept me more disciplined—not only in sleep, but also in my morning walk routine (at least 1,700 steps), and in other aspects of my health. I feel like I’m taking better care of myself each day.

[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.] Bought my ring at the beginning of the year as an add-on to my Apple watch. Am fairly happy with all the features and measurements. I do find that my Apple watch workouts aren't always syncing correctly with the UH app. So that’s a bit annoying. Also not happy with the Tesla integration feature. But all in all, readings and pretty good and keeps me on track.
