[This review was collected as part of a promotion.] I bought the ring back in May on a whim and now I am OBSESSED! I love to use it to track my sleep and learning overall how to have a better night of sleep. It is so light and holds a charge well! I only have to charge my ring every 3-4 days!

[This review was collected as part of a promotion.] I bought the UH over the Oura ring because there is no monthly fee. So far I am enjoying my ring, I find the sleep data the most inciteful but also really enjoy the caffeine suggestions. The battery life is not as good as I expected, some days it is worse than others. There is an option to preserve battery with a certain setting but it does limit some of the data collected so I haven't played around with that yet. I am interested to see how well it tracks my cycle as I plan to come off of Birth Control in the coming months.

[This review was collected as part of a promotion.] I find the ring such a helpful tool to keep track of my sleep and encourage me to look after myself. It helps me focus on my sleep and my self care generally. Gently reminding me when to move more or lay off the caffeine. The main thing it has helped me with is getting sunlight first thing in the morning to help regulate my circadian rhythm. I feel more in control of my habits as I can check in with the app anytime to see what my body is dealing with.

[This review was collected as part of a promotion.] I’ve really enjoyed seeing these statistics, especially the sleep score. As a mom, I also love the “new parent” plug in that accounts for rest + mindfulness moments. As far as design goes, I love the look and after a few days of wearing, barely even notice I’m wearing the ring. Overall, would recommend!

Ultraring Review: A Small Ring with a Big Edge After two weeks with the Ultraring, it’s safe to say this isn’t just another wellness tracker. It’s a sleek, lightweight powerhouse that delivers deep health insights without the bulk of a smartwatch or the friction of another screen. What I loved: Next-level sleep tracking: Not just duration, but quality, readiness, and recovery cues that actually helped me adjust my routine. Subtle and stylish: It blends seamlessly with my everyday look. No blinking lights, no distractions — just data when I want it. Battery life that holds up: I got nearly a full week on a single charge, which makes it easy to forget I’m even wearing tech. More energy - I follow the caffeine intake and my energy levels in the afternoon are night and day! What could be better: I don't get a period due to surgery and Id love it to suggest potential cycles based on temp so I can still track something.

[This review was collected as part of a promotion.] I bought it about 6 months ago, I still wear this ring every day to track various aspects of my health, especially my sleep. I usually find wearing a watch annoying, so this is a better alternative. Plus, it also serves as a fashion accessory.

[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 first in May, and it stopped working in a week's time. The second time, I received the ring from Ultrahuman as a replacement for the faulty ring; this time the ring stopped functioning in 20 days' time. This has to be one of the worst products that I have bought. Once the ring runs out of battery, the ring will not turn back on.

[This review was collected as part of a promotion.] I love the ring, when it takes a charge. Only had for a few months and wear it daily. I am having a serious issue with the ring not taking a charge. Im a little disappointed for the price i paid and already having issues.

[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.
