[This review was collected as part of a promotion.] I picked this up mainly for sleep tracking (I don't like to sleep with my Apple Watch). I changed the setting to max statistics (which uses the most battery) and just charging it when I get ready for bed or hop in the shower is enough to keep it going. At first I wasn't sure how accurate the data was (the first few days with it the ring said I was asleep while I was watching TV), but after a few days the accuracy improved. Then the first day time I got a cold it asked me the next morning, if I was feeling sick because my temperature was elevated and I had a horrible night of sleep! I did wind up putting black electrical tape over most of the charging LED, that thing is bright enough to light up my entire room, even when the ring isn't connected to it. There's really no need for it to be illuminated when the ring isn't on it.

[This review was collected as part of a promotion.] While the ring itself is good, I’m not happy with the app experience. The information that’s presented is very confusing and I am unable to understand some of the details it shows like phase advance, etc. The accuracy of its detection of my activity is very poor. The app sometimes shows activity detected and asks me if I want to add it and most of the times it doesn’t. The tagging is very bad, I can’t find the tags I want. If I add a custom tag, it won’t get stored so that I can reuse it. The type of workouts are not comprehensive. App leaves a lot to be desired with features, user experience and functionality.

[This review was collected as part of a promotion.] Have been using the ring for more than a month now, and what blows me away the most is the accuracy of the insights. Sleep tracking is the feature I like and use the most, and the ring being very comfortable to wear to bed is what helps. There is no manual input needed post initial setup, just wear it and consume the insights. This is the best tech purchase I’d made in the last couple of years.

[This review was collected as part of a promotion.] I've had my Ultrahuman AIR ring about for six months now, and it's changed my life. I can't believe how granular and specific the data is. Logging my food, the app made suggestions for how to improve my nutrition, which I incorporated. Tracking my sleep, it tells me when I'm not sleeping enough, when my sleep is disturbed, and it makes recommendations for how to improve my circadian rhythm and sleep cycles, which I have incorporated. For example, it can tell when I've eaten too late or consumed caffeine too late causing worse sleep performance. A feature I really love is the stress data. It perceives my stress and is incredibly accurate! I love how it tells me this, and then I try to incorporate behaviors, which it suggests, to improve my stress, such as meditation activities, working out, and earlier sleep. Then there are the weekly reports and body signal readings, which delve into particular health details to tell you what's going right or wrong about your body's biodata at a particular time. Also, I love the cardio age and Ultra age estimates, which gives me insight into tracking how I'm aging. I had a smart watch tracker for many years before this smart ring purchase, and they were requiring frequent replacement due to burn-out and provided hardly any of the data-driven health insights that the Ultrahuman AIR ring does. And then there's the fact that it is a handsome piece of jewelry on my finger, and the battery life is great requiring infrequent charging. I just can't rave enough. I've told all my friends and strongly encourage anyone who is interested in data and genuine information about their body and health to purchase and use the Ultrahuman AIR smart ring. It changed my life and I love it!

[This review was collected as part of a promotion.] Iv had my Ultrahuman ring air for a few months now and getting to grips with the various insights is making life a little easier. The few patters I have picked up on have allowed me to change habits to work towards a healthier life.

[This review was collected as part of a promotion.] Have had the ring four a couple of months now and overall am I happy with it. The pulse feels sometimes to high and a miss more detailed data of my running workouts. I don’t find any running apps that I can connect the ring with which would be great.

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring AIR for several weeks now and I’m genuinely impressed. The design is sleek and lightweight — I forget I’m even wearing it. Sleep tracking is incredibly accurate, and I love how the app gives me actionable insights every morning. The battery lasts for nearly a week, and it charges surprisingly fast. I also appreciate the fact that there’s no subscription needed — it’s a one-time purchase with full access to the features. This ring has become an essential part of my daily routine, from tracking workouts to improving recovery. Highly recommended!

[This review was collected as part of a promotion.] it helped me ditch, my smart, watch and opt for something a lot more friendly with my life. I love the app and I especially love the really informative sleep tracking that has really changed how me and my partners see our sleep and we have one of those shared groups on the app where we get to compare our stats throughout the day, which is also very challenging when it will say who is in first place or who’s in second place and I really like the workout mode, which has been really helpful and I’ve been a lot more active recently, which has been such a great positive change for me.

[This review was collected as part of a promotion.] Thoroughly enjoying this fitness tracker! I've mad my ring for 2 months now and it is one thing that I rarely take off. I purchased it out of interest and wanting better sleep insights as I struggle with sleep consistency. Let me tell you, I got much more than I was expecting. The insights providing are amazing! There's so much information that I have yet to learn to interpret all of my daily/weekly insights fully. As a woman, I was interested in the cycle tracking and those have been interesting. I have noticed that the insights do change based on the data received and input on the app - which I appreciate.

[This review was collected as part of a promotion.] I am very happy with the app, the comfortably and easy usage of the ring. Also I like the ongoing improvements and additions. The only improvement I have is that once my ring was broken, it took quite a while to get an replacement because I had to do several firmware updates before it was agreed to get a replacement. The support was always super quick and helpful but this I found a bit dissapointing.
