[This review was collected as part of a promotion.] I have loved my ring since I purchased a few months ago. The battery lasts awhile after being fully charged. I love the health insights it gives me and truly makes me more conscious of health choices, for example my step count and sleep health. It gives recommendations to improve certain health insights that are actually helpful. I would recommend this ring,

[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 bought this ring 2 months ago and had issues the first weeks as its sleep readings differed greatly from my fitbit- which I also wear to sleep. After several weeks tho, the difference between the 2 wearables are not that big so I guess it has calibrated tho there are still days that it seems off.

[This review was collected as part of a promotion.] I bought this 3 months ago, I was really happy with the device and the software, and happy to see you're pushing updates very often with new feature. But the ring doesn't work anymore since a week ago. The battery runs out after a few hours, even after charging it completely. Something has somehow... changed, and it doesn't work as it should anymore. I've updated the firmware, and run diagnostics, but nothing fix the issue. Which im quite disappointed now, I can not use it and I have no data about myself since the issue started. I have a ultramarathon this weekend and won't be able to use it.

[This review was collected as part of a promotion.] I bought this ring when I was looking for a smart ring to detect my activity especially my sleep and also my fitness. From some brands, I totally like this ultrahuman. Battery life is not the best but still enough to last for minimum 5 days. A bit expensive though but compared to the accuracy data it gives, it still worth it.

[This review was collected as part of a promotion.] After a couple months I will say I enjoy the content. I appreciate the efforts to improve it. I think it has some weaknesses that should be fixed. Taking measurements every five minutes is not enough. The battery recharging isn’t practical - I always lose multiple days when I need to recharge. The gaps in heart rate are too frequent. Make it vibrate or something if it isn’t picking up. The inability to record during a round of golf or a tennis match stinks. Thinner would be better. The age thing is in conflict - one part of the software says I’m younger by two years and another says I’m older by a few years. The sleep data isn’t as granular as other sleep trackers. I wrote all this because I love the product. I am writing because I care.

[This review was collected as part of a promotion.] I purchased this ring to help track my sleep, fertility, and movement. I love the data available to me from body temp, to my sleep quality (which needs improvement!), and tracking my activity (especially the reminders to get up to stretch and/or move). The only downside is the battery life. I have it on the lowest battery setting (chill mode) and still feel like I need to charge it every other day. I love that purchasing the gold ring wasn’t a difference in cost (as compared to competitors) and that I don’t have to pay extra for cycle tracking!

[This review was collected as part of a promotion.] I recently switched over from a forever Apple Watch to the Ultrahuman Ring AIR. Instead of establishing unrealistic goals and allowing my watch to control my life, the Ultrahuman ring helps me track my health in a way that is just that - healthy. I like that I can see my caffeine window, stress levels, track my cycle, and monitor my sleep patterns. Also, the ring is so cute and less bulky than a watch!

[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 brought the Ultrahuman ring AIR back in March. It’s been really insightful knowing the internals of my health, how my sleep can impact my recovery and mood throughout the day. The caffeine window has been really helpful. The menstrual cycle tracking has helped me understand my body more. I would totally recommend buying, I have influenced many of my friends to get it.
