[This review was collected as part of a promotion.] I got it in March and already have the second replacement because it stopped connecting after a firmware update, so now I don’t update the firmware because I’m scared it will stop connecting again. But I am super happy with it when it is working

[This review was collected as part of a promotion.] I’ve been using the ring for about two months now, and overall I’m very happy with it. The ring hasn’t discolored at all and still looks like new. It’s very comfortable to wear, even while sleeping or during workouts. I use it regularly for strength training, and it never gets in the way or feels uncomfortable. It’s especially great for sleep tracking — very accurate and insightful. One downside is that you can’t see things like calorie burn in real time; you only get the data afterward. Also, the battery life is a bit shorter than advertised. I usually get about 4 to 5 days per charge. Still, compared to a smartwatch, this is already a big improvement for me. All in all, I’m really satisfied with this ring and would definitely recommend it for anyone looking to track sleep and activity in a more subtle way.

[This review was collected as part of a promotion.] I love my ultra human ring… I have learned a lot about my sleeping patterns, what affects them, and what I can do to improve my sleep however, I do feel that the battery life is horrible. I have to charge my ring twice a day

[This review was collected as part of a promotion.] I rate the sleep tracking but the other functions aren't great. Tracking 'activity' and 'workouts' is limited; setting up a workout only tracks heart rate & gobbles up battery, whilst logging backdated activity isn't giving me any data at all anymore, I don't know if there is something wrong with my ring? It often struggles to sync and the battery doesn't last more than 2 days. I would love the dev team to take this on board and make improvements. Also, the gold has colour dulled and scratched within a few months despite claiming to be waterproof etc.

[This review was collected as part of a promotion.] I've had the ring since February 2024 and have loved it since day one. My main goal was to track and improve my sleep — and I’ve managed to do both. The missing star is due to occasional issues with the app not syncing properly with my fitness tracker (Strava). I usually don’t wear any ring during workouts (rowing, training, etc.), which sometimes causes the ring to misinterpret the lack of activity.

[This review was collected as part of a promotion.] I have purchased my ring ca. 3 months ago and using it ever since. What I like: - sleep tracking - caffeine window - workout tracking - workout tracking - new parent function :) - the UI has a nice appeal - no subscription What I would change: - bad connectivity with ring-phone - long updating times between ring and phone (updated app, reseted phone, meanwhile changed to new phone) - every time ring update is available I have to reset the whole ring since it remains stuck updating The overall appeal of the ring is positive with some throwbacks, mostly SW related. If new ring will be available on the market, I highly consider upgrading :)

[This review was collected as part of a promotion.] I bought the Ultrahuman Air ring a while back and it has been one of the most used device to track my health. At the moment of the purchase, I was constantly having troubles with my sleep and it has been really useful to be able to see the stages of each night. I also really loved the other features, especially the dynamic recovery and the advices it comes with. The only downside I found is that there are differences between my watch and ring inthe movement scores, but nothing too massive. The battery life had change over time, now it is shorter, but I also know that I had it for quite some time. I also love how there are all sort of updates, both in the app and the firmware and how you can see that the developers really care about their products. I would really recommend it

[This review was collected as part of a promotion.] I am very pleased with this ring! I tell everyone I get a chance to about it. The ring is sleek and comfortable on my finger. I have been wearing it for about 5 months and I don’t notice any chips or cracks at all. I purchased it as the most cost effective way to track my sleep, steps, and menstrual cycle. I have been tracking my cycle for a few years but this has taken it to the next level and given me more accuracy. The battery life is really good, I only charge my ring every 4 or 5 days. Definitely satisfied with my purchase!!!

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring Air for a while now, and it's become a really useful part of my daily routine. One of the standout features for me is how it tracks and helps me understand my sleep. I get detailed insights each morning—not just how long I slept, but how restful it was, my recovery levels, and what might be affecting it. Another feature I really like is the caffeine window. Based on my sleep data, it recommends the best times to avoid caffeine, which has actually helped me feel more rested and alert during the day. The ring also sends nudges throughout the day, reminding me to move when I've been sitting too long or encouraging me to hit my movement goals. It’s subtle, but effective in keeping me more active. Overall, the Ultrahuman Ring Air is lightweight, comfortable to wear all day, and packs a lot of smart features that support better health habits without being overwhelming.

[This review was collected as part of a promotion.] I have been enjoying the ring as a tracking device. I have had to switch from smart watches due to skin rash, loving the lightness of it and no skin issues! One downside is the loading time, for example steps they're not reflecting live on the app. Another thing I wish for if it's less bulky, and has nicer finishes.
