[This review was collected as part of a promotion.] I have had this ring for about 2 months now and love it. I am not usually super into this stuff, but the insights are unreal. I mostly wanted it to count my steps and help me with my sleep, but it does so much more like my stress levels, caffiene, and insights on my cycle. I also thought it would be uncomfortable but I barely notice it, and the only ring I wear is my wedding rings.

[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.] I’ve been using the Ultrahuman Ring for several weeks now, and I can confidently say it’s become an essential part of my health and fitness routine. What sets it apart for me is how seamlessly it tracks sleep, recovery, and overall readiness without being bulky or intrusive. I wear it 24/7, and often forget it’s even there. Sleep tracking has been especially impressive. The insights into my deep sleep, REM cycles, and HRV have helped me make meaningful changes to my bedtime routine. I’ve noticed that on nights where I prioritize wind-down, my ring reflects the quality improvement—and I feel it too. The daily recovery score is one of my favorite features. It helps me decide whether to push hard in the gym or take a lighter day. It’s like having a coach who reminds me to listen to my body without the guesswork. I’ve noticed better energy levels and fewer slumps since I started using the ring to guide my training intensity.

[This review was collected as part of a promotion.] Overall, I'm very happy with my Ultrahuman Ring AIR. The tracking features are great, the battery life is good, and the app is very user-friendly. My only complaint relates to the fading of the ring over time. I have had my ring for just under 1 year and it has gone from gold to mostly silver due to fading.

The Ultrahuman Ring Air stands out for its lightweight, comfortable design (It is barely noticeable), and super-long battery life. I love the Gold finish!! It monitors my sleep. I keep it in Turbo mode, which tracks the maximum amount of data, and still averages more than six days per charge.

I bought my ring secondhand but brand new. The person I bought it from told me that they sent their original ring back because the battery life significantly dropped after just over a month of use. Ultrahuman sent her a brand new ring which I then bought from her - and I've had the same experience. The battery used to last several days and now it maybe lasts a day and a half. I've only had it for a few months. Battery life aside, I do enjoy exploring the information provided, particularly my sleep scores, cycle, and movement throughout the day.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring for a few months now, and I can confidently say it's one of the best health and wellness devices I've ever owned. What truly stands out for me is the incredible sleep tracking. The insights it provides are not only detailed but also actionable. I can now understand how different habits affect my deep sleep, REM cycles, and overall recovery. The best part? The ring is so comfortable, I forget it’s even there. It’s on my finger 24/7—through workouts, showers, and while I sleep—and it never feels intrusive. The continuous monitoring gives me a full picture of my health, but sleep tracking is where it really shines. The app is intuitive, and I love how it breaks down complex sleep metrics in a simple, visual way. I’ve genuinely improved my bedtime routine and energy levels thanks to the guidance it provides. If you're serious about improving your sleep and overall well-being, I can't recommend the Ultrahuman Ring enough.

[This review was collected as part of a promotion.] The ring is great for the tasks it’s supposed to do- help regulate sleep schedule, workout summaries & for me personally help track my menstrual cycle & my caffeine intake & schedule. Unfortunately it does not stay charged for long than 2 days & that’s being generous. I’ve only had my ring for about 3-4 months & the charge only last about 24-36 hours. I was really hoping it would stay charged for at least a week. Overall I did like it & how sleek it is compared to other fitness tracking devices. I would recommend, but be aware of battery life.

[This review was collected as part of a promotion.] I’ve been testing the Ultrahuman Ring Air, and it’s quickly becoming a valuable tool for monitoring recovery, sleep, and overall readiness. The design is sleek and comfortable, making it easy to wear around the clock without disrupting daily activity or training sessions. What stands out most is the depth of insight provided. HRV tracking, sleep stage analysis, and metabolic health markers are presented in a way that’s both actionable and easy to interpret. The seamless integration with Ultrahuman’s ecosystem adds another layer, allowing for a more holistic approach to athlete monitoring and personal performance optimization. For anyone serious about understanding their body’s response to stress, recovery, and training load, the Ultrahuman Ring Air offers a level of precision and usability that’s hard to match. I’m excited to continue exploring how this can support athletes at the elite level.
