[This review was collected as part of a promotion.] Heart disease runs in my family, and even though I try to stay active, I’ve never really known how well my heart is actually doing. Not just on the outside, but internally—like how fit it really is. This ring has been surprisingly helpful. The Cardio Age feature kind of freaked me out at first, but it was also a wake-up call. Seeing that number was a good push to take things more seriously—and what's cool is that I could actually see it improve a bit after a couple of weeks of better sleep and more consistent workouts. The VO2 Max reading is another feature I didn’t expect to care about, but now I check it way more often than I probably should. It’s satisfying to see it climb, even slowly. And cardio adaptability is probably what I’ve appreciated the most. It tells me how well my body is bouncing back from stress or workouts—and for someone with my family history, that feels like gold. As for the design, honestly, I’m not a huge fan of chunky wearables, so I was relieved that the ring looks clean and minimal. It doesn’t scream “fitness tracker,” which I love. Super light, too—I forget I’m wearing it most of the time. Heart disease runs in my family, and even though I try to stay active, I’ve never really known how well my heart is actually doing.

Especially if, like me, you're trying to stay a step ahead of genetics.

[This review was collected as part of a promotion.] My Ultrahuman Air ring has been my 24/7 every-day companion for everything health – from giving me insights into my sleep, optimal caffeine intake, or social jetlag, to exercise, aging rate, and a ton of other data that helps provide me with insights that enable me to maximize my everyday life. And with regular (sometimes weekly!) software updates thanks to the Ultrahuman team, my experience only gets better and better!

[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 the ring experience and the changes in lifestyle it triggers if you engage in this journey. I definitely changed my behavioural patterns for the better, and I like the sleek jewelry look that I can (and do) wear with any outfit. Unfortunately I’ve had quite some battery issues after a few months, but these are being taken care of.

[This review was collected as part of a promotion.] The UltrHuman Ring is a sleek, comfortable wearable that delivers impressively accurate health tracking. From sleep quality to heart rate variability, it provides clear, actionable insights through an intuitive app. The long battery life and durable design make it perfect for everyday use. Since using it, I’ve noticed real improvements in my energy and wellness. If you want a smart, effortless way to optimize your health, the UltrHuman Ring is a game-changer!

[This review was collected as part of a promotion.] Battery degrades prematurely. I bought hardly used second hand ring air and was offered to purchase ultrahumanX extended warranty through the app. Turns out ultrahuman warranty is non-transferable. As a customer I feel like this company does not stand behind their product and I would never buy their product. There are other well know smart ring companies that has transferrable warranty and stand behind their product.

[This review was collected as part of a promotion.] My Experience After a Few Months I’ve been using the Ultrahuman Ring for several months and overall, I’m quite satisfied with it. The ring itself is well-built and comfortable, though I expected it to be a bit smaller. Despite this, it fits well for daily wear and doesn’t interfere with my activities. App Features The Ultrahuman app offers a wide range of features, which I find impressive. It provides detailed insights into various health metrics such as: • Sleep quality • Recovery scores • Activity tracking Heart rate monitoring • Readiness and metabolic health However, the app interface could be more user-friendly. At times, it feels a bit cluttered and overloaded with information. It would be helpful if the app presented key insights more concisely, allowing users to quickly understand their status and what actions to take. Suggestions for Improvement • Simplify the Dashboard: A cleaner overview with only the most important data points would make daily use easier. Actionable Tips: Short, clear advice for each health area (e.g., how to improve sleep or recovery) would be beneficial. • Customization: The ability to customize which metrics are highlighted on the main screen would help users focus on what matters most to them. What I Would Like • Quick, summarized information for each health topic. • Clear, actionable steps to improve performance in areas like sleep, recovery, and activity. • A less crowded and more intuitive app interface. Conclusion The Ultrahuman Ring is a solid health wearable with strong hardware and valuable insights. With some improvements to the app’s clarity and usability, it could become even more effective for users seeking quick, actionable feedback on their health and performance.

[This review was collected as part of a promotion.] Love the ring :) I was initially hesitant to buy it since I assumed it would not be as accurate as a watch for Sleep and Activity tracking. Ultrahuman Ring AIR proved me wrong, and I'm glad it did :) The insights from their app are very useful (even though I may not like some of them, like telling me not to drink coffee now :D ). I understand my sleep patterns a lot better because of them.

[This review was collected as part of a promotion.] The battery needs to be charged more often than expected unless I turn it down to only track the minimal (sleep etc). Maybe it being in the sauna drains the battery or when I used to click a functional workout real time maybe that is also draining the battery. Lastly, I have the silver, and there are lots of hairline scratches on it and it feels like plastic on top. Maybe there can be other cooler finishes like textured to help disguise the scratch potential? Otherwise cool and lots of info and options.

[This review was collected as part of a promotion.] The experience has been great so far. I have been tracking my fitness and recovery scores regularly from the ring, and it's helped me plan my routines much better. I have been working out for quite some time now, and I am always trying to figure out ways to optimize what I can get out of my lifestyle. We all know that sleep and recovery is a huge part of living a fit life, and somehow that has been consistently lacking from my routine. Bought this ring to be more mindful around my sleep and recovery, and honestly haven't been disappointed
