[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 bought the ring approximately 6 months ago. Unfortunately after 2 months it died and I was n out able to connect it anymore. Thank to the support we solved everything and I got a new ring in two weeks. Since than I have experienced no issues. I would say in general only positive things about it when it comes to tracking. I really like how the ring measures my sleep efficiency and that for every metric it gives actual explanation what it means and how to improve it. Also things such as dynamic is crucial for me as for an athlete. The battery is not the best but in chill mode it is ok

[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.

overall i enjoy my ultrahuman ring! waking up everyday to check my sleep data is so interesting. tracking all of the times i shift or when im in deep sleep is so interesting to see! also i like that it can track your bodies stress level. as a paler person i also love the vitamin d feature! i like how it tells me how long i have until i burn depending on the uv level! my only con of the ring would be how easily it scratches.

[This review was collected as part of a promotion.] This ring was gifted to me for mother's day. It was a surprise, and i wasn't sure it was going to be for me, but I love it! I love how simple the tracking is - no bulky watch to wear - only some beautiful jewelry.

[This review was collected as part of a promotion.] The Ultrahuman ring is a great alternative to the Oura ring. The app is very functional and easy to use breaking information down, unlike the Oura ring. The ring offers important insights into your health allowing you to make subtle changes to your lifestyle for the better. Love the ring and would recommend it to anyone in the market for one.

[This review was collected as part of a promotion.] I got it in March and already have the second replacement because it stopped connecting after a firmware update, so now I don’t update the firmware because I’m scared it will stop connecting again. But I am super happy with it when it is working

The Ultrahuman Ring is a game-changer, and I'm hooked! Easy to use, accurate, and stylish - what more could you ask for?"

The Ultrahuman Ring AIR is light, comfortable, and packed with useful health insights. It tracks sleep, recovery, and movement accurately, and the app is easy to use. Battery life is solid, and the ring looks great too. A great choice if you want to improve your health without wearing a bulky device

[This review was collected as part of a promotion.] Initially everything worked wonderfully, then I noticed ongoing issues with the charge. It takes a significant amount of time to charge, then the battery drains very quickly. In addition, it has just not worked all day today and is prompting me to complete a factory reset, losing all my data. The dashboard is not showing anything or collecting any info. It often disconnects while I workout and will not let me end my workout session. At first the sleep features with the caffeine windows performed amazing and were game changers.
