[This review was collected as part of a promotion.] Loved the ring initially but I’m having frequent occurrences of it disconnecting and taking a lot of work to reconnect. I’ve been trying for 2 days to get it to reconnect with my phone. Contacting Support today.

[This review was collected as part of a promotion.] I am really happy with the ring - I like the sleep stats (which I need to improve), the vitamin D stats, cycle tracking, etc. So much good stuff to improve your health. I like that I don't need to wear a watch or something bulky. It also picks up my walks easily, but I do turn on the workout mode for pilates/etc. Battery lasts like 4-5 days for me with daily workouts.

[This review was collected as part of a promotion.] i bought this ring a couple of months ago. however, contrary to expectations mentioned in the booklet I am having to charge the battery every 3rd day. Secondly there are too many health parameters being displayed which are confusing. Otherwise I am happy to be using the product, thanks

[This review was collected as part of a promotion.] The Ultrahuman Ring has been an amazing tool. It's helping me understand how to optimize my sleep with precise measurements and recommendations. The information provided is actionable, which is something not found with wearables I've tried in the past. It's helping me build better eating and sleeping habits and I strive to get 90s when I can. The ultra human age is something I've been working to improve and also a feature I haven't seen on my wife's Oura ring. It's been great to see my brain age get younger with better sleep habits. The additional features such as breath work have been fun to use when I do my red light/IR therapy sessions. It's become my constant companion and I have only ever taken it off for charging (the battery life is outstanding). The alarm clock that syncs with my sleep cycles is also a neat feature. Overall, very happy with my purchase. At first thought I was making a mistake of owning both an Apple Watch and the ring, but they each have their uses!

[This review was collected as part of a promotion.] Ultrahuman Ring is great. It nicely complements my portfolio of smartwatches with other useful data. It is nicely made, has good battery life and is comfortable to wear. As a tester of smart devices, however, one thing is not going through my head. The HRV value. Although it is within the norm according to the application, it absolutely does not correspond to the values from my watch. And I am testing two models at once, where the HRV almost matches, while the ring shows completely different values. So somehow I can't figure out what algorithm it works on. The same goes for the accuracy of the heart rate sensor, which also needs to be fine-tuned. There is also a small but unpleasant error in the translation of the application. As a Czech, I prefer the Czech language, and the translation is very basic, so some translations in the final do not make much sense. Otherwise, I am satisfied with the product.

[This review was collected as part of a promotion.] I’ve been testing the Ultrahuman Ring Air, and it’s quickly becoming a valuable tool for monitoring recovery, sleep, and overall readiness. The design is sleek and comfortable, making it easy to wear around the clock without disrupting daily activity or training sessions. What stands out most is the depth of insight provided. HRV tracking, sleep stage analysis, and metabolic health markers are presented in a way that’s both actionable and easy to interpret. The seamless integration with Ultrahuman’s ecosystem adds another layer, allowing for a more holistic approach to athlete monitoring and personal performance optimization. For anyone serious about understanding their body’s response to stress, recovery, and training load, the Ultrahuman Ring Air offers a level of precision and usability that’s hard to match. I’m excited to continue exploring how this can support athletes at the elite level.

[This review was collected as part of a promotion.] I purchased the Ultrahuman Air after considerable research. I don’t like wearing a watch/wristband and I wanted something to track my health. The good: it is lightweight and the battery lasts forever. The tracking that it does is consistent and the data seems good (although it’s hard to verify). I have used the data to pinpoint problems with my sleep that I can address. The bad: it really only tracks movement, heart rate, and sleep phase. Everything else is derived from these. I would love to expect to have more data. O2 saturation, EKG, galvanic skin response, etc. The amount of data and insights are disappointing.

[This review was collected as part of a promotion.] I am very pleased with this ring! I tell everyone I get a chance to about it. The ring is sleek and comfortable on my finger. I have been wearing it for about 5 months and I don’t notice any chips or cracks at all. I purchased it as the most cost effective way to track my sleep, steps, and menstrual cycle. I have been tracking my cycle for a few years but this has taken it to the next level and given me more accuracy. The battery life is really good, I only charge my ring every 4 or 5 days. Definitely satisfied with my purchase!!!

[This review was collected as part of a promotion.] I bought it 3 months ago and sometimes i have problems conecting to the app and downloading the information ? And it was a period of tine like 2 weeks the ring died completely , not even charging it the app could found the ring

[This review was collected as part of a promotion.] After a full year, the Ultrahuman Ring has proven to be more than just a gadget—it’s a health companion. It has helped me become more intentional with my sleep, recovery, and overall wellness. I highly recommend it for anyone serious about optimizing their lifestyle with data-driven insights.
