[This review was collected as part of a promotion.] I bought this ring two months ago and have been using is consistently - it had not disappointed! Really cool features and easy to use app interface, definitely the best health tracking ring you can find out there. Some measures do not feel completely accurate (sleep is sometimes a bit off, as well as movement is undercounted) but overall, compared to what most other fitness trackers offer, this is really good. I have tried various fitness trackers over the years, mostly watches, and the ring is much more convenient, highly recommend.

[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.] 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 purchased my Ring AIR back in March and I’m very happy with the results. It has made me more aware of my sleep patterns, sunlight exposure and overall health. It’s very important for me to keep track of these items because if my sleep hours are low then it can affect me during my daily routine. The ring is comfortable and no issues with wearing it while I sleep. It does charge pretty fast which is convenient. Overall, happy with my purchase!

Love the detailed tracking and interpreted insights which the Ultrahuman Ring gives. It's not just raw data, but the insights derived from it that make all the difference. The build quality is top notch - I've never had to worry about scratching it (matte black variant).
