[This review was collected as part of a promotion.] I have been using ring about year... 1. Would like to get access raw data , like blood O2 , as my hobby is flying would like to monitor what height does. 2. App send far too many notifications - less would be enought

[This review was collected as part of a promotion.] Initially was great very quickly went down hill. Has struggled with connectivity and battery life, dies in a day and a half maybe two days sometimes on chill mode. It constantly wouldn’t track my sleep data and would show 2-3 hours of a 8 hour sleep. I have already requested a refund for the clearly faulty product. If you can fix these issues I’d be interested in continuing to use Ultrahuman as I do believe the product and what you are towing to achieve

[This review was collected as part of a promotion.] I got it in March and already have the second replacement because it stopped connecting after a firmware update, so now I don’t update the firmware because I’m scared it will stop connecting again. But I am super happy with it when it is working

[This review was collected as part of a promotion.] I’ve been using the ring for about two months now, and overall I’m very happy with it. The ring hasn’t discolored at all and still looks like new. It’s very comfortable to wear, even while sleeping or during workouts. I use it regularly for strength training, and it never gets in the way or feels uncomfortable. It’s especially great for sleep tracking — very accurate and insightful. One downside is that you can’t see things like calorie burn in real time; you only get the data afterward. Also, the battery life is a bit shorter than advertised. I usually get about 4 to 5 days per charge. Still, compared to a smartwatch, this is already a big improvement for me. All in all, I’m really satisfied with this ring and would definitely recommend it for anyone looking to track sleep and activity in a more subtle way.

[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.] This is one of the best purchases I’ve ever made. I really love the ring — it looks great, feels great, and works reliably. What I value most is that the Ultrahuman Ring does not require a subscription. That was a dealbreaker for me — I didn’t even consider rings like Oura. I’m happy to pay significantly more (even 30% more) for a device if it offers strong baseline functionality with no recurring fees. Please never move core features behind a paywall — that would be a reason for me to stop using it. I’m strongly against subscription models as the only entry point. I’m fine with paying for optional add-ons — that model makes sense and I’m even considering a few. One small improvement I’d love: slightly longer battery life, maybe +1–2 days. Otherwise, amazing product.

[This review was collected as part of a promotion.] I’m thoroughly impressed with the Ultrahuman Ring AIR. The build quality feels premium — lightweight, comfortable to wear, and beautifully designed. What stands out the most is the accuracy of its health tracking. From heart rate and HRV to sleep and daily activity metrics, the ring provides consistently reliable data that helps me better understand my body and lifestyle. The app integration is also seamless, offering clear insights and helpful suggestions without being overwhelming. Battery life is great, and charging is quick and hassle-free. One word: Impressive. This ring has become an essential part of my wellness journey.

[This review was collected as part of a promotion.] I have been using the ring for over 6 months now after deciding to move away from Apple Watch, my 8 years of companion. I think it’s been life changing, especially for sleep tracking and overall wellness with the convenience of wearing nothing. After the patch that I wore experimentally few years back, this is my second product from Ultrahuman and super happy.

[This review was collected as part of a promotion.] I absolutely love my ring!! Getting such an in-depth look at my daily metrics and what affects my sleep has really helped me prioritize better habits and make sleep more important to me. It’s very accurate, super easy to use, and I have had literally zero technical issues. Love this ring so much!!!

[This review was collected as part of a promotion.] I love the constant updates and insights on the app. The only downside is the quick battery life. I change it to chill or critical battery mode when low. I usually keep it on chill for most of the time.
