[This review was collected as part of a promotion.] I bought my ring 4 months ago and I have mixed feelings. I love how light and sleek it is. I get compliments on the look of it all the time. I prefer it over wearing a watch. I love the sleep insights and all the data it collects. However, my one con is that the battery life is terrible. It took a while for the ring to calibrate to a place where the battery lasted a few days on a full charge but now after 4 months post-purchase I had to get a replacement because the battery dies within hours after a full charge. For the price, I would hope the item would last way longer.

[This review was collected as part of a promotion.] I purchased the ring in August last year and have enjoyed its features so far. However, I've noticed the battery has been draining very quickly recently, lasting less than a day, which is quite frustrating.

[This review was collected as part of a promotion.] Very happy with my Ultrahuman ring, i can’t use a watch because it hurts my wrists, so the ring was perfect for me! I like how it looks and feels. Only problem I have is that the ring disconnect when i am running and have Headphones connected at the same time as the ring, so i don’t get step count or pulse readings on that workout.

[This review was collected as part of a promotion.] Overall i am mid happy with it, but I bought to use the period tracking and it still says in calibration. Moreover it is not possible to add an activity afterwards bc it just says no data, I can only add it if it auto tracks it. The sleep tracker is also off, it makes no sense the amount of deep sleep I get

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’ve been using the Ultrahuman Ring for a while now, and it’s genuinely transformed the way I approach my health and lifestyle. What initially drew me in was the sleek design and the promise of actionable insights—but what I didn’t expect was how deeply it would shift my mindset toward long-term wellness.

Ring is a good fit and able to give feedback that I need. I am using the ring mainly to track my sleep and steps. It is more convenient than a watch which can be bulky. It is also more comfortable to wear this to sleep since it is small. Data seems to be very close to my Garmin watch, so I believe that the data is relatively correct.

[This review was collected as part of a promotion.] The Ultrahuman Smart Ring has been an absolute game-changer for me. Its sleek design is incredibly comfortable for 24/7 wear, and I barely notice it's there. The data it provides on sleep, activity, and recovery is incredibly insightful and has helped me make tangible improvements to my health. I particularly love the detailed sleep analysis and how it helps me understand my readiness for the day. The battery life is impressive, lasting several days on a single charge. If you're looking for a smart wearable that's both stylish and delivers actionable health insights, I highly recommend the Ultrahuman Smart Ring.also I love ❤️ it, been using 2years .

[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.
