[This review was collected as part of a promotion.] I really like all the things this ring measures. It's very interesting to watch how what I do in the day affects my sleep that night, from the HR drop to sleep cycles and the length of each phase. Very helpful and interesting, definitely don't regret buying.

[This review was collected as part of a promotion.] First of all, having no subscription for your device is something that made me end up with Ultrahuman. I’ve purchased the ring 3 months ago, but already had a replacement due to a faulty battery. The tracking capabilites regarding excersises and doing basic stuff like walking seems to be all over the place, while the sleep tracking and all the insights (caffein window for example) that the app gives based off of those metrics are exactly what i was looking for. The design and the sleep tracking was the inital reason i bought the device and in those areas it meets my expectations. Overall, a nice tracking device thats stylish as well (and have no distracting haptic feedback or screens!) but fitness tracking still has room for improvement.

[This review was collected as part of a promotion.] I love my ultra human ring… I have learned a lot about my sleeping patterns, what affects them, and what I can do to improve my sleep however, I do feel that the battery life is horrible. I have to charge my ring twice a day

[This review was collected as part of a promotion.] I’ve had my ring for almost a year and I’ve loving it so far being able to see my sleep data everyday and know what I can do to improve it. Along with I love that I can use it to track my steps and workouts and don’t have to wear anything else.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring AIR for a few weeks now, and the difference in sleep quality and recovery is night and day. The real-time biomarker insights (especially HRV and skin temperature) gave me more control over my routine and helped me make smarter lifestyle choices. It’s not just a tracker - it’s a personal performance optimizer. Looking forward to more firmware upgrades and continued improvements. Great product, strong ecosystem.

[This review was collected as part of a promotion.] Ultrahuman Ring Air has been a lifesaver in tracking my sleep as I am not able to sleep with a watch on. The sleep, caffeine, and recovery insights are very useful in improving my quality of life each day. Also, the build quality and look is great!

[This review was collected as part of a promotion.] I have been using the ring just over a month now. Swapping from Apple Watch. I have been exclusively wearing the ring without an Apple Watch for the past week too. Much more comfortable to sleep with, no notification distractions and better overall health tracking. Battery life better than a smart watch too so less hassle. If you want a fitness tracker without a screen it’s top tier in my opinion!

I’ve been using the Ultrahuman Ring Air for 3 months now and I’m hooked. Having previously used the Apple Watch, I found myself abandoning it after a while due to the constant need to charge it. In contrast, the Ring Air lasts 2–3 days on a single charge, powers up quickly, and is far less intrusive — no sweaty wrists or discomfort. The ring is light, comfortable, and effortlessly fits into my daily routine. Every morning, the first thing I do is check my sleep score on the app — it’s intuitive, detailed, and helps me understand where my sleep might’ve fallen short. The health insights are practical and motivating. Overall, it’s a sleek, smart, and reliable companion for anyone serious about improving their health without the fuss of a bulky wearable.

My experience has been great so far, I have loved all the features the ring has to offer. However, recently the ring has not stayed connected and will not collect sleep data because of this. I did purchase the warranty, so I am hoping this process is smooth and the issue can be resolved quickly. I’ve really enjoyed my ring so far, so I am eager to have it replaced or back to working condition.

I’ve had my ring for a month now and it’s dramatically improved my sleep and recovery. The caffeine window is a helpful feature and the movement score makes me more likely to get extra steps in. I’ve found the ring great for tracking runs and your zone training but the only con so far is that I have to remove the ring when I am at the gym so it doesn’t scratch.
