[This review was collected as part of a promotion.] I've had this ring for almost 2 months and it has helped me better my sleep and shown me that I need to move my body more. Love the caffeine tracking feature and cycle tracking so far has been spot on even 2 months in.

[This review was collected as part of a promotion.] Earlier I was using Apple Watch which was cumbersome to wear at all time especially during sleep and charging daily was an issue .Since I have started using Ultrahuman I am happily tracking my daily activities especially sleep and calories with a good battery life.the best feature is the alarm clock which will wake you up according to your REM sleep which will make you feel fresh on getting up. It correctly calculated my sleep deficits,sun exposure,heart rate variability and dynamic recovery .. all of which is required to be monitored to stay fit in this stress driven world .Ultrahuman is amazing

[This review was collected as part of a promotion.] I have had this ring about four months now and it has been the greatest! Charge last a couple of days and it is always giving me accurate information! It has been a game changer for my health issues with my doctors as well. I can share the information with them very easy!

[This review was collected as part of a promotion.] I bought my ring a couple of months ago, based on personal recommendations and reading reviews. I tested the template rings first, which is a great idea to ensure you pick the correct size and also the colour you prefer. Set up is simple and I was able to use it straight away. I’ve found that the step count numbers vary quite a lot from both my Apple Health and Fitbit phone tracking apps and also my Garmin watch. The counts are significantly lower than all the others. This may be because it is more accurate but it was very surprising, given the others were all at similar levels. I don’t find some of the app metrics overly useful as yet, and feel like the sleep score could be part of the overall dynamic recovery measures. The jet lag measure just displays the same info most of the time too. The caffeine metric is one I have been using a lot and find value in this one, which is good. Also not having to pay a subscription is a big benefit. Overall, I’m glad I’ve tried it but do think there is room to improve on a number of factors, to take it to the next level.

[This review was collected as part of a promotion.] I am really enjoying my Ultrahuman ring! I love seeing my sleep score when I wake up and tracking my stats throughout the day. It has really helped my daily and sleep routine to become more productive. I really appreciate that Ultrahuman is always adding new features, insights, and small little changes that help the overall function of the ring. The only thing I wish was an option, was to sync my apple health data to my ring as well, instead of just syncing my ring data to my apple health as this sometimes leads to double counting of steps, etc.

[This review was collected as part of a promotion.] For a long time I was looking for something that would measure everything like a smartwatch. And I found something way better, and comfortable in use. Very user- friendly app and very accurate measurements/predictions.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Air Ring for a while now, and it has quickly become one of my favorite health and fitness gadgets. The first thing that impressed me is how lightweight and comfortable it feels. I often forget I’m even wearing it, which is perfect for 24/7 tracking. The ring tracks key health metrics like sleep, heart rate, and activity levels with impressive accuracy. I especially like the sleep insights—it doesn’t just tell me how long I slept, but also provides recovery scores and actionable suggestions to improve rest. The activity tracking is equally useful, helping me understand my daily movement and energy expenditure without the bulk of a smartwatch. The companion app is sleek and intuitive, with clear visualizations and trends that make the data easy to digest. I also appreciate the nudges and insights it gives for improving recovery and performance. Battery life is solid; I can go several days without charging, which is a huge plus for continuous tracking. If I had to point out one minor area for improvement, it would be expanding the integrations with more third-party health apps. But overall, the Ultrahuman Air Ring is a fantastic investment for anyone looking to monitor and optimize their health without wearing a traditional fitness watch.

[This review was collected as part of a promotion.] I love the data the ring provides! It has been really interesting seeing what affects my sleep and hoe I can make improvements to help shape how I feel throughout the day. My only negative is how long it takes to charge. I want to wear it at all times to get the data. It would be nice if it could be fully charged in 30 mins so I don’t have to have it off for so long. Overall an amazing product!

[This review was collected as part of a promotion.] I do believe that the product is good. Would I buy it again? I don’t know. Does it have something to do with the product itself? Probably not. I bought it to motivate myself to sleep better - I thought that if I get a ring that tells me I need to fix my sleep and I will pay for it then I will take it seriously and improve my habits. That didn’t really happen. I can, however, see the improvement over time in the product. The constant updates are actually adding very nice festures and fixing bugs! The battery life is good and the measuremements make sense. So far, the best function for me was hody temperature monitoring. It helped me predict when I was gonna get sick and made me take it easy on some days which has in the end resulted in me not getting sick! Pretty cool!

[This review was collected as part of a promotion.] I bought this 3 months ago and I have no regrets. I love how it shows not only data, but insights as well. It really helped me monitor metrics that I want to keep track of, especially sleep and caffeine flexibility. I appreciate how the app seems to be improving all the time, adding new things like ultra age and brain waste clearance. It motivates me to do better and take care of myself more. Plus, I get to wear my nice (non-smart) watches without having to think that I'll miss any important data. Highly highly recommend!
