[This review was collected as part of a promotion.] I love how much information I am receiving regarding my sleep. The ring even gives me a caffeine window. I can see the ring is responsive to what is going on in my life. When I exercise consistently my cardio age is lower than when I have fallen out of the exercise habit. I gave it four stars because I wish it gave me more insight into my monthly cycles. I am glad I purchased my ring. I choose this ring because of the no subscription fee. I love my ring!

[This review was collected as part of a promotion.] I bought this 3 months ago, I was really happy with the device and the software, and happy to see you're pushing updates very often with new feature. But the ring doesn't work anymore since a week ago. The battery runs out after a few hours, even after charging it completely. Something has somehow... changed, and it doesn't work as it should anymore. I've updated the firmware, and run diagnostics, but nothing fix the issue. Which im quite disappointed now, I can not use it and I have no data about myself since the issue started. I have a ultramarathon this weekend and won't be able to use it.

[This review was collected as part of a promotion.] I've had the ring for several weeks now and I like how detailed the information is. I still have so much more to learn and options to try like the breath work. I know I need to make changes to improve my health and the ring is helping me focus on what I need to improve

[This review was collected as part of a promotion.] I love my Ultrahuman ring. Having insight into my sleep and recover has been eye opening. It has made me make changes in my sleep hygiene so that I get a better deep sleep and ultimately a better recovery. The reasons I didn’t give it a 5 are: the battery really only lasts 3-4 days, I am unable to wear it while I Olympic weight lift so I can’t track my workouts and it seems to be quite different on the step counter then my Apple Watch which I wear on the same hand. Besides that I think having it has made a very positive improvement in my overall health and I’m happy I bought it.

[This review was collected as part of a promotion.] I bought this ring when I was looking for a smart ring to detect my activity especially my sleep and also my fitness. From some brands, I totally like this ultrahuman. Battery life is not the best but still enough to last for minimum 5 days. A bit expensive though but compared to the accuracy data it gives, it still worth it.

[This review was collected as part of a promotion.] It's been a little over a month since I started using it but it still surprises me with scarily good insights it constantly provides during the day. I mainly bought it for sleep tracking but this thing is surprisingly good at fitness tracking as well. I specifically enjoy the recovery score. It made me much more cautious about my caffeine usage and screen time. Can't wait to see more benefits the more I keep using it!

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring for a couple of months now, and I genuinely think it's a brilliant alternative to smartwatches—especially if you're someone like me who prefers classic watches over digital ones. This little device has significantly improved my quality of life, drawing my attention to things I had never really considered before, like sleep quality and my personal favorite feature: the “caffeine window.” It’s surprising how much insight such a small ring can offer. I never thought it would have such an impact—not just on my awareness, but also on my daily habits. To be honest, I didn’t expect it, but the ring has even helped me lose weight in just 2–3 months. One small piece of advice: if you're considering buying one and plan to lose weight, get a size that's almost too small. I went with a comfortable fit at first, but after shedding some weight, the ring became a bit loose and now sometimes rotates on my finger, making it harder for the sensor to collect data consistently. Highly recommended—this is probably one of the smartest investments I’ve made in my health.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring for a little while now, and it’s been a game changer for my health and wellness! Not only is it sleek and comfortable to wear 24/7, but the insights it provides into my sleep, recovery, and metabolic health are next-level. I’ve tried a few other fitness trackers before, but this one feels much more intuitive and personalised. The app is beautifully designed, and I love how it translates all the data into actionable tips- it’s helped me improve my sleep quality, manage stress better, and stay more consistent with my workouts. The recovery scores are spot on, and it’s made me more mindful of how my habits impact my overall performance and energy levels.

[This review was collected as part of a promotion.] The ring is amazing to use, best wearable possible. Sleep tracking is what I use most. Then the caffeine window. App is beautifully designed and has a lot of information. Would recommend to anyone who is considering.

[This review was collected as part of a promotion.] I got this at the end of 2024 and love it! The only thing I will say that I wish was different was the battery life. Even when keeping up with the updates to the app and the firmware, I feel like battery life has decreased. Other than that, I think it’s a great tool if you’re into wellness and learning more about your body!
