[This review was collected as part of a promotion.] The ring has helped me understand my body better. First of all, the sleep metrics are very helpful. Ultrahuman sends me notifications Concerning my optimal time when I should go to bed and in the morning lets me know how I did. Also super is the information about the caffeine window and the fact that you can enter the drinks you consume. The ability to log workouts is also great. Battery life is optimal. The ring's software is update frequently so you can see new features coming and the Ultrahuman gets better every day. I heartily recommend it.

[This review was collected as part of a promotion.] I have been using the ring just over a month now. Swapping from Apple Watch. I have been exclusively wearing the ring without an Apple Watch for the past week too. Much more comfortable to sleep with, no notification distractions and better overall health tracking. Battery life better than a smart watch too so less hassle. If you want a fitness tracker without a screen it’s top tier in my opinion!

[This review was collected as part of a promotion.] Have had the ring for 1 year now and has been great. Build quality is good, no physical issues. Consistent updates have improved functionality. Some updated caused issues with battery life but subsequent updates have corrected any problems. I have a smart watch and the data between the 2 devices is very similar, with the ring providing a what I feel is more accurate sleep data than the watch.

[This review was collected as part of a promotion.] I love the ultrahuman AIR ring! I hate having screens around me so a smart watch was out of the question. After a lot of research I settled on the AIR ring because there is no monthly subscription. I love all of the insight this piece of technology gives me! Sleep, heartrate, and cycle tracking! It has even predicted when im getting sick. The only reason this is not a five star review is because the battery life is not what is advertised. If you want it to last longer than a few days you have to sacrifice tracking.

[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.

[This review was collected as part of a promotion.] I’ve been using it now for 2 months and am really happy overall with my experience. As a runner, I find all of the cardio age and vo2 max statistics really helpful and it’s been great to see them changing the longer I use the ring. The battery is good, I charge it whilst I’m at my desk every few days or so and it’s relatively fast to charge to full battery. My only reason for not giving it 5 stars is the period tracking. I was under the impression that as it measures your body temperature it would predict cycle outcomes based on this, not just 28 days. As someone with an irregular period, if it is late, the app just says that my period is in an unknown phase. It seems to basically be their own version of an app such as flo. I don’t find it to be any more accurate, despite the body temperature measuring.

[This review was collected as part of a promotion.] I bought it 3 months ago and sometimes i have problems conecting to the app and downloading the information ? And it was a period of tine like 2 weeks the ring died completely , not even charging it the app could found the ring

[This review was collected as part of a promotion.] Bought this mainly for sleep tracking as hate Apple Watch in bed. The ring is light reliable and get 5-6 battery without worrying about it. On top of that I really like the app and the insight it provides on top of sleep tracking, If your on the fence about purchasing I would go ahead and do it

[This review was collected as part of a promotion.] The Ultrahuman Ring has been an amazing tool. It's helping me understand how to optimize my sleep with precise measurements and recommendations. The information provided is actionable, which is something not found with wearables I've tried in the past. It's helping me build better eating and sleeping habits and I strive to get 90s when I can. The ultra human age is something I've been working to improve and also a feature I haven't seen on my wife's Oura ring. It's been great to see my brain age get younger with better sleep habits. The additional features such as breath work have been fun to use when I do my red light/IR therapy sessions. It's become my constant companion and I have only ever taken it off for charging (the battery life is outstanding). The alarm clock that syncs with my sleep cycles is also a neat feature. Overall, very happy with my purchase. At first thought I was making a mistake of owning both an Apple Watch and the ring, but they each have their uses!
