[This review was collected as part of a promotion.] Very comfortable to wear, highly recommend using the sizing kit to ensure you get the right size. The app provides A LOT of insights and does a good job of explaining why it’s important to health and wellbeing. I’m 4 months in and still learning and adapting my sleep, caffeine and exercise routine.

[This review was collected as part of a promotion.] I bought this in April and have worn it everyday since, really enjoy the sleep and cycle data this provides. And no monthly subscription! For anyone looking to purchase highly recommend, and fit wise make sure you can wear on multiple fingers to account for size fluctuation’s when it’s warm etc..

[This review was collected as part of a promotion.] Im mostly happy about the fact that i don’t have a monthly fee for insights, the sleep score and the fertility tracking. I do think the battery life could be longer, but the new feature that helps control battery usage has helped. I also am not the biggest fan of the newest insight called ultra age. It’s not very clear on what it tracks and kinda contradicts the other cardio/heart age insight. I wish the ultra age would give you better understanding of the factors and how to improve it. It also doesn’t pick up on the times i work out and i just figured out how to add them after. But i wish it would intuitively pick it up and ask “did you work out?” like it does for the nap.

[This review was collected as part of a promotion.] Up until a week ago it was working fine, registering my values efficiently. After the latest update however, the battery doesn’t last a whole day anymore. When it was new I didn’t need to recharge it for approximately 3 days. I like wake up function (found a favourite tune) and I use it almost daily. I don’t have a second devise to compare the functions to so can’t really say much about its accuracy. However, I chose this ring above Oura simply because it doesn’t require a subscription to see the more complex values from recording your sleep. Another reason for choosing this over Oura was the aFib detection and cardiofunction, but I got quite disappointed from learning that these two functions require a subscription. On the plus side I like the layout and I find the info about all things it contains to be interesting.

[This review was collected as part of a promotion.] Bought the ring, n it has helped me to managed my sleep pattern better. I try and keep to my exercise regime during phase change periods and avoid caffeine and simulants during recommended periods. I can see results! Better sleep, improving VOMax2 and slowing ageing!

[This review was collected as part of a promotion.] The ring was my big christmas present 2024 and I‘ve been in love with the ring ever since. I like the features and especially the constant strive for improvements though I feel like the app design was prettier before the „big“ update. One thing I find quite interesting is the discreptency in steps between my iPhone und the ring with the latter always being lower even though I don‘t carry my phone everywhere with me. Overall I‘m very happy and would recommend the ring to everyone who wants a smart ring.

[This review was collected as part of a promotion.] After having the ring for a couple months, I've enjoyed seeing the information presented for my health. The data is presented in a clear manner and gives some assistance on improvement when necessary. My only negative is the battery. Initially, the battery was lasting a out 5 days between charges. Recently, it has been an every other day requirement. This isn't a major problem and become just another routine activity to plan in my day/evening.

[This review was collected as part of a promotion.] Best investment in my health in a long time. It's been incredible to have instant access to so much useful data in such a simple and easy to understand way. I only need to glance and I have so much information throughout the day. I originally got this purely for the sleep tracking but I have quickly found every aspect of the ring useful - the insights I'm getting are so worth it. It's also such a plus not having to pay a monthly subscription for the app.

[This review was collected as part of a promotion.] I've been using the Ultrahuman Ring AIR for a few weeks now, and I’m genuinely impressed by how seamlessly it fits into my daily routine. It’s incredibly lightweight — I often forget I’m even wearing it — yet it delivers deep insights into my sleep, recovery, and metabolic health with impressive accuracy. What stands out most is the attention to detail in both the hardware and the app — the data is not only detailed but also easy to understand and act on. I’ve used other fitness trackers before, but this one feels far more focused and refined. The app’s nudges and insights are personalized without being overwhelming, and it’s been a real eye-opener in improving my sleep patterns and recovery habits. Overall, it’s a premium product that’s clearly built with purpose. Highly recommended for anyone serious about optimizing their health and performance!
