[This review was collected as part of a promotion.] I absolutely love the ring it’s helped me improve my sleeping pattern and help with my overall focus on my health. My only issue is the charging dock, I don’t know why when I put it on the dock I have to keep moving it to keep it charging. Don’t know if I’m doing something wrong or what.

[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 my ring in June and I’ve been primarily using it to track my sleep! I find it gives very accurate readings and is really good at giving me suggestions and graphing my data. The only reason I gave it four instead of five is that the ring scratches super easily. I have the gold and a lot of it is basically silver at this point. I don’t wear rings around it at all so it’s not rubbing on anything. The battery is okay, I charge it probably every 3 to 4 days. I was hopeful it was going to last longer. Also, often when I go into the app, it takes quite a while to load my data and I have to refresh it quite a few times.

[This review was collected as part of a promotion.] Bought the ring avout 2 minths ago and it gives me most if the details I was looking to track my sleep. I’d be looking for an improved exercise tracking functionality in the future. App is complete and insightful.

Took a couple tries to get the right ring size. I like all of the things it shows, sleep, steps, stress, cycle tracking and heart rate. Some days I don’t feel the sleep is as accurate, but maybe I’m a worse sleeper than I thought! Overall I like it. The app is easy to use.

[This review was collected as part of a promotion.] Have had the ring for 1 year now and has been great. Build quality is good, no physical issues. Consistent updates have improved functionality. Some updated caused issues with battery life but subsequent updates have corrected any problems. I have a smart watch and the data between the 2 devices is very similar, with the ring providing a what I feel is more accurate sleep data than the watch.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring Air for the past few weeks, and it has quickly become an essential part of my daily routine. This sleek, lightweight wearable packs a serious punch when it comes to health tracking, offering a perfect blend of performance insights, recovery metrics, and personalized recommendations. Design & Comfort: First off, the design is stunning — minimalistic, elegant, and discreet. Unlike bulkier smartwatches, the Ring Air feels virtually weightless and looks great with any outfit. I often forget I’m even wearing it, which is a testament to its comfort. Metrics & Accuracy: The data accuracy has been impressive. From HRV and sleep cycles to movement and skin temperature, the insights feel both comprehensive and reliable. The sleep tracking is especially detailed, helping me pinpoint areas to improve my rest and recovery. App Experience: The Ultrahuman app is intuitive and thoughtfully designed. It doesn’t just throw numbers at you; it contextualizes them with actionable suggestions and clear visualizations. I particularly like how it integrates metabolic and circadian insights to help optimize performance and recovery. Battery Life: The battery life is stellar — I’ve been getting 5–6 days on a single charge, and the charging case is compact and easy to carry. Conclusion: If you're serious about your health, sleep, and performance, the Ultrahuman Ring Air is absolutely worth the investment. It's not just a fitness tracker — it’s a powerful tool for anyone looking to live smarter and optimize their everyday well-being. Highly recommended!

[This review was collected as part of a promotion.] I'm obsessed with my Ultrahuman Ring Air! The design is sleek and stylish, and it's so comfortable to wear. Since getting the ring, I've made it a habit to check my sleep index every morning and my movement index at the end of the day. It's amazing how it's helped me stay on top of my health and fitness. Love it!

[This review was collected as part of a promotion.] I have had this ring for an about 4 months. I really enjoy the heart rate monitoring for exercise. I’m not big on wearing a watch, so this is a nice alternative. It does seem to be easily scratched or beat up, but so far that hasn’t affected how the ring works. I also didn’t realize how much I was enjoying tracking my sleep.

I bought the Ultrahuman Air approximately 2 months ago and I'm content with it. I haven't had any problems with it so far. My only complaint is that when I bought the ring, it was advertised with a battery life of up to 6 days. I can go about 3-4 days in between charges and I have it on chill mode. I have the raw titanium color and it gets scratched pretty easily. Other than that, I love the ring.
