I wanted the ring for sleep tracking and it is perfect for that. And tons of feature without a monthly fee.

[This review was collected as part of a promotion.] I bought the ultra human ring in April and have been wearing it everyday. I love the sleep feature and the period tracker as it is more accurate that my existing app I had. I have started taking it more seriously how and when I am sleeping to improve my sleep score.

[This review was collected as part of a promotion.] The Ultrahuman Ring Air has completely changed the way I understand my body and health. One of the biggest benefits has been the clarity it provides around my energy levels—I can now pinpoint exactly why I’m feeling tired or off on a particular day, and the app highlights areas I can actively work on to improve. I was genuinely surprised to learn that my sleep quality wasn’t as good as I thought. The detailed sleep insights made me more mindful about my routine and helped me make small changes that have had a big impact. Comfort-wise, the ring is exceptional. It’s light, sleek, and feels like a natural extension of my body. I barely notice it, even while sleeping. I’ve also tested it in pretty rough conditions—during gym workouts, heavy weightlifting sessions, and outdoor runs—and it’s held up flawlessly. Extremely durable. Only downside: The app tends to consume a significant amount of battery in the background, even when the ring isn’t actively connected. I hope future updates address this issue. Overall, highly recommended if you're serious about understanding and improving your health.

[This review was collected as part of a promotion.] I've had my Ultrahuman AIR ring about for six months now, and it's changed my life. I can't believe how granular and specific the data is. Logging my food, the app made suggestions for how to improve my nutrition, which I incorporated. Tracking my sleep, it tells me when I'm not sleeping enough, when my sleep is disturbed, and it makes recommendations for how to improve my circadian rhythm and sleep cycles, which I have incorporated. For example, it can tell when I've eaten too late or consumed caffeine too late causing worse sleep performance. A feature I really love is the stress data. It perceives my stress and is incredibly accurate! I love how it tells me this, and then I try to incorporate behaviors, which it suggests, to improve my stress, such as meditation activities, working out, and earlier sleep. Then there are the weekly reports and body signal readings, which delve into particular health details to tell you what's going right or wrong about your body's biodata at a particular time. Also, I love the cardio age and Ultra age estimates, which gives me insight into tracking how I'm aging. I had a smart watch tracker for many years before this smart ring purchase, and they were requiring frequent replacement due to burn-out and provided hardly any of the data-driven health insights that the Ultrahuman AIR ring does. And then there's the fact that it is a handsome piece of jewelry on my finger, and the battery life is great requiring infrequent charging. I just can't rave enough. I've told all my friends and strongly encourage anyone who is interested in data and genuine information about their body and health to purchase and use the Ultrahuman AIR smart ring. It changed my life and I love it!

[This review was collected as part of a promotion.] I bought this ring a couple of months ago and I am more than satisfied with the information it gives me regarding my overall health. I particularly use it for sleep and heart monitoring, in conjunction with my exercise and medications needed.

[This review was collected as part of a promotion.] I just love the Ultrahuman ring. Eversince I've started using the UH ring, my life and health have started improving and I make smart lifestyle choices. Awesome work UH team. Keep up the good work 💪

[This review was collected as part of a promotion.] I bought the ultra human ring about 2 months ago and so far I’m loving it . I had an Apple Watch previously but I really like that the ring focuses more on overall health insights as opposed to exercise. The sleep score and cycle tracking are my favorites and I enjoy seeing how my sleep ties to my overall health.

[This review was collected as part of a promotion.] I bought this like 4 month ago. I really like the amount of health stats and the optionol plugins. I sometimes wish that workout tracking would somehow trigger automatically, because I often forget to start a workout on the phone.

The ring has been outstanding. I use it to monitor my sleep, sleep debt, dynamic recovery, and various other features. The ring's durability has been excellent so far. I have the matte black version. I engage in normal daily activities like washing my hands and doing dishes, and there are zero scratches so far. The battery life has also been impressive. I appreciate that I do not have to pay a monthly subscription.

[This review was collected as part of a promotion.] I bought the ring a couple months ago and I love it. The features that the ring has are really interesting to see and the app does a good job explaining all the different stats. I really appreciate that all the features are free and you can add new ones based on what you want to see. My only complaint is that if you run the ring on turbo mode (to see your stress levels) the charge only lasts a little over 24 hours.
