Stopped working after 2 months
[This review was collected as part of a promotion.] Stopped sending data to my app after about 2 months of use and the battery dies after a few hours - doesn’t last a full night. I tried resetting it, followed all of the prompts, but nothing will fix it. Basically completely useless and a total waste of money.

A Year Later and Still Impressed
[This review was collected as part of a promotion.] I’ve had my Ultrahuman Ring for almost a year now, and I’m still really enjoying it. It’s given me a lot of insightful data that’s helped me better understand my sleep patterns, identify foods my body doesn’t agree with digestively, and even recognize when my immune system might be compromised. The insights have made me much more aware of how my body responds to different habits and routines. And one of the best parts is that all of this comes without a monthly subscription.

Excellent sleep and cycle tracking!
[This review was collected as part of a promotion.] I've been using the ring for over half an year now and Im super happy with it. The activity tracking for sports could be better but since I tend to use a sekretem device for this im not too bothered. Sleep tracking is excellent but I think cycle tracking was the biggest game charger for me. I never rememberd to track my cycle and now that ist done pretty much automatically I've started connecting my symptoms to my cycle and discovered my healh issues are due to perimenopause. The data collected made it so much easier to advocate for myself with my health provider! No subscription is also key here!

Got other wearables before
[This review was collected as part of a promotion.] I used many other wearables in the past, but was impressed by the Ultrahuman Ring Air. A big plus for me was its affordable, subscription-free price. Initially, it was the practical form factor that attracted me, and pairing capabilities with the most popular smart watches and iOS and Android phones. Easy to wear, fashionable, super light, and comfortable to wear all the time. No need to remove around water, thanks for being waterproof. I discovered a new world of advice on better health and well-being. Impressed by the sleep, stress, cardio reporting, AFIB, recovery, and brain age, stress management data, and amused by the accurate caffeine window. Not perfect but improving daily, with WhatsApp 24/7 customer service when needed.

Best smart ring in the market
[This review was collected as part of a promotion.] The Ultrahuman Air Ring has become one of my favourite health gadgets. It feels like nothing on my finger, the build quality is excellent, and the recovery/sleep data has genuinely helped me make better training decisions. The app feels smarter and more intuitive than most wearables, and the daily insights are actually actionable. If you care about recovery without wearing a bulky watch 24/7, this is a no-brainer.

Lots of data!
[This review was collected as part of a promotion.] Overall, I like this product a lot. There are a lot of cool features, data to analyze, and they display it for you in a way that is digestible and not overwhelming. I like the suggestions it gives you based off of different patterns you have. The best thing I like it for is the sleep analysis, and the score it gives me. It gives me insights I haven’t had before! Although now that it is a year out from me having it, I did start having some performance issues like it not tracking data completely.

The best ring ever
[This review was collected as part of a promotion.] I love the fit of this ring! They send you out a measuring ring size kit with multiple basic ones to test for a day to get the perfect fit! It tracks stress aswell as sleep and heart rates! I love the scoring system it does too! I never understood the value for money after testing this and it’s top of the marks

Useful sleep metrics, activity tracking needs impr
[This review was collected as part of a promotion.] I use Ultrahuman ring everyday and most of the data points are reallyuseful, sleep cycle info in particular. However, their activity tracking still needs inprovement i.e. it records steps when I'm riding a motobike and does not pick up other activity like pilates even when I upload them manually. Really hopethis will be corrected with further software updates

Not worth the money
[This review was collected as part of a promotion.] DON'T BUY IT! I bought my ring in the spring and already will not hold a charge longer than 7 hours. I have done multiple resets on the ring, checked all settings to ensure other apps are not draining the battery and still will not hold a charge. Since it will not hold a charge longer than the 7 hours, i cannot even use it to gather data on my sleep, limited thru the day as well and have to charge it just to even track steps. Buy the Oura!
