Great product for measuring sleep and workouts!

[This review was collected as part of a promotion.] I got this as a gift 3 months ago and it works perfectly! I use it primarily for tracking my sleep and workouts to get an overview of my progress. The one feature I use the most (and is also the reason I got interested in the product) is the caffeine measurement. My sleep has gotten way better after limiting the caffeine consumption in regards to what the app says. Also a thing to note is that i got the ring with titanium coating and I'm surprisingly amazed of how little the scratches are visible on the ring after 3 months use. Overall a great product!

good product!

overall i enjoy my ultrahuman ring! waking up everyday to check my sleep data is so interesting. tracking all of the times i shift or when im in deep sleep is so interesting to see! also i like that it can track your bodies stress level. as a paler person i also love the vitamin d feature! i like how it tells me how long i have until i burn depending on the uv level! my only con of the ring would be how easily it scratches.

Great piece of hardware!

[This review was collected as part of a promotion.] I am completely satisfied with my Ultrahuman Air ring. I bought it a few months ago and I can already feel a noticeable shift in many things. My sleep has improved. I know when to rest more and when to exercise more. It has also improved my caffeine intake, which has had an effect on my sleep. Great piece of hardware!

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。

Accurate data

[This review was collected as part of a promotion.] I recently purchased this ring for the sole purpose of improving my sleep and overall health. I do have an Apple Watch as well but find that I can easily sleep with the ring on and do not notice it at all. The health data it collects is extremely accurate especially for sleep! I have been able to make some changes to my night time routine based on suggestions from the app and have improved my sleep. The battery is great and holds up well, I often only charge it when I shower and have never gotten a low battery alert. I can wear it for the entire weekend without charging it which is nice if on vacation. The only reason I gave it 4 stars vs 5 stars is that I found the gold to scratch very easily. Although you can’t tell until you close it’s unfortunate as only a couple months old.

Love this ring!

[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.

My personal commitment partner to wellness!

[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.

Comfortable!

[This review was collected as part of a promotion.] I have had this ring for about 2 months now and love it. I am not usually super into this stuff, but the insights are unreal. I mostly wanted it to count my steps and help me with my sleep, but it does so much more like my stress levels, caffiene, and insights on my cycle. I also thought it would be uncomfortable but I barely notice it, and the only ring I wear is my wedding rings.

Very good buy, I definitely recommend!

[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.

Great product and keeps getting better!

[This review was collected as part of a promotion.] I've been really satisfied with the Ultrahuman AIR. It's made a noticeable difference in both my sleep and morning routines. One of the biggest improvements I've seen is how much quicker I fall asleep—something I used to struggle with. The insights provided by the device have been genuinely helpful in understanding and optimizing my habits. I'm also really excited about the new tag system and what it will bring. It looks promising and could add even more depth to the insights and tracking. If I had to point out a downside, it would be that the step count seems to be underestimated compared to other devices I've used. It's a minor issue, but worth noting. Overall, it's been a great addition to my wellness toolkit.
