[This review was collected as part of a promotion.] I love the ring and love that I don't have to pay for access to the data compared to other brands like Oura. Love that the ring can track activity and naps without having to manually enter the appropriate mode (auto tracks). The only issue I have is that the battery life is gotten noticeably worse - about a month and a half into wearing it it stopped lasting me a few days and needs daily charge. Is this normal?

[This review was collected as part of a promotion.] I bought the ring 3 months ago after comparing it to several other 'smart rings' and I am so glad I chose this one. Mainly I use it to track my steps and heart rate as well as sleep. The app has a ton of features and is easy to learn to use.

[This review was collected as part of a promotion.] I've been using my ring for a few months now and I've already recommended it to multiple friends. It has encouraged me to move more, get more steps daily and increase my sun exposure. The period tracking is very reliable as well. The ring has been able to detect trends and sleep patterns that I never would've discovered otherwise which has allowed me to totally change my nighttime routine to improve my sleep. I've been a big fan so far!

[This review was collected as part of a promotion.] I have been a customer since Ring R1 for the ease of use for health tracking (especially sleep), and when they launched the Ring Air it just got even better with all the useful functionalities in an even smaller form factor. Just crazy how tech has evolved.

[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 had the Ultrahuman ring for about a month though and I’m liking it overall. It has been great for tracking my sleep and I haven’t had any battery issues. The app has a lot of data which is great, but my one complaint is that it is a little bit overwhelming and hard to navigate.

Wearing the Ultrahuman ring feels like second nature — it’s incredibly sleek and comfortable. What sets it apart is how intelligently it translates my body’s signals into actionable insights. From sleep quality to recovery patterns, it’s like having a personal coach on my finger. Highly recommended if you're serious about improving your health in a sustainable way.

[This review was collected as part of a promotion.] I've been using the UH Ring Air for approximately two months now, and overall, I'm very satisfied with my experience. Initially, I was expecting a battery life of 3-4 days, but I was consistently getting around 36-48 hours. However, following several software updates, a "Chill Mode" was introduced, which has significantly improved my battery life, even when using Turbo Mode. Unfortunately, I opted for the gold model, which shows scratches more easily; in hindsight, I would have preferred the black version.

[This review was collected as part of a promotion.] 7 months into the ring and it's getting worse by the hour. It doesn't even hold a charge for 24 hours any longer, ever since it has been exposed to the chill mode... so I miss out on sleep tracking, don't dare to track fitness.

[This review was collected as part of a promotion.] I have enjoyed using the Ultrahuman ring. The sleep tracking works well. I like that they continue to add functionality and improved the battery life with new modes. I wish I could use this to track my heart rate when I exercise but does not seem to be able to capture that accurately. Lastly tends to accumulate a fair amount of scratches that don’t seem to heal as advertised. Love that there are no subscription fees.
