[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring AIR for a few weeks now, and the difference in sleep quality and recovery is night and day. The real-time biomarker insights (especially HRV and skin temperature) gave me more control over my routine and helped me make smarter lifestyle choices. It’s not just a tracker - it’s a personal performance optimizer. Looking forward to more firmware upgrades and continued improvements. Great product, strong ecosystem.

[This review was collected as part of a promotion.] I bought this a month ago. I'm happy with some things but disappointed with the workout data received. I gave up my smartwatch and bought this ring. But, there has been major glitches in data accuracy. I worked out for 60 mins and it showed 54 calories burnt. I mean how strange is that?

[This review was collected as part of a promotion.] I wrote this as my review: Love the app for the ring. I've gained good insights into what affects my sleep for better or worse. The insights from the ring are much, much more in depth than I initially thought before I bought the ring. I had learned that while my sleep was good, my "morning alertness" was a big cause of why I felt so tired, so I've made major changes to stop checking my phone first thing in the morning and get moving instead. I knocked off one star mostly for battery life -- wish it were better. Other than that, I've stopped wearing my fitness watch in favour of the ring for its small form factor and detailed tracking.

[This review was collected as part of a promotion.] Love my UltraHuman Air ring. Things a love about it is the sleep tracking. Definitely been feeling more energised after going to bed and waking up on time. Also like tracking how my fitness levels are tracking. Would recommend this ring to anyone

[This review was collected as part of a promotion.] The Ring has been a helpful assistant for my health. The ability to have a device that is lightweight, and minimalist makes me forget that I’m wearing it at all. I love how insightful the device is, been able to track sleep, heart rate patterns and caffeine intake were things I need in a device and this ring does all those factors right.

[This review was collected as part of a promotion.] I bought this ring 2-3 months ago and it has been a game changer. I love this ring. The powerplugs really enhance your experience and you can really understand your body better. The only negative thing I have about this ring is that I purchased the cardio adaptability but I have not seen it provide any actually insights. There is no section for cardio adaptability and no way to really see how it helps you experience. I don’t know if I have to activate my subscription but there has also been no button to do that. Overall great health tracking and sleep tracking.

[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've been using Ultrahuman for a while now, and overall, I'm extremely satisfied with the product. The sleep tracking is detailed and accurate, the step count is reliable, and the heart rate (HR) and heart rate variability (HRV) metrics are consistently well-presented. The app interface is smooth and insightful, making it easy to monitor and improve daily wellness habits. The only area where I see room for improvement is automatic activity detection. While common movements like walking are well tracked, activities such as swimming, intense yoga, and jogging often go undetected, and I have to manually log them. It would be great to see the ring better recognize a wider range of workouts on its own. That said, this is a minor issue compared to the overall value the platform offers. Looking forward to future updates that make an already excellent product even better!

[This review was collected as part of a promotion.] Been a month and a half since I’m using it. This has definitely been transformational for me because a lot of the patterns that my body portrayed are now finding logic because of the ring. I have changed my sleeping habits, eating time, etc. The only issue I feel right now is charging. I’m never able to charge it to 100% because the only time I take off the ring is in the morning for about 40-50 minutes before I’m ready to leave for work. Other than that it is GREAT!

[This review was collected as part of a promotion.] I have been using ring about year... 1. Would like to get access raw data , like blood O2 , as my hobby is flying would like to monitor what height does. 2. App send far too many notifications - less would be enought
