[This review was collected as part of a promotion.] Bought the Ring AIR about five months ago, mainly because of the no-subscription business model, and the other reason was for sleep tracking. It has been amazing to see trends over time, and the ability to easily access all the data as a csv file has been really helpful. Only a few days ago I decided to improve my sleep with supplements, and after four days of taking two of them (magnesium glycinate and L-theonine) I've seen measurable improvement. Having data regarding sleep stages, sleep time and other metrics like HRV and temperature drop has been super-helpful. I wear the ring all the time, and am happy to start tracking my workouts now as well. Highly recommended!

[This review was collected as part of a promotion.] I purchased the ring in November 2024 and received it in December. Since then, I’ve worn it continuously while taking great care to avoid exposure to harsh products, including removing it for showers and workouts. Despite this, I’m surprised by how much the gold color has faded and the usage is seen - with 8 months of usage it’s more than I expected. That said, I really love the product overall and appreciate the valuable insights it provides, along with the regular updates and new features.

[This review was collected as part of a promotion.] I've been using the ring air for over a year now and the experience has been nothing short of great! I love the evolution of body metrics and insights, and the interplay of different features interactions to help optimize my sleep and recovery. Highly reccomend!

[This review was collected as part of a promotion.] Ultrahuman Ring AIR is an excellent product that helps me track all my physical activities, and monitor my heartrate, HRV. I have been using it for last 6 months and with the increase in my cardio, the correlation i see in dropped heartrate is amazing. The caffeine window and circadian rhythm are such a great add on. The sleep scores are so accurate and i can always see how that score correlates to my mood and energy for the entire day.

[This review was collected as part of a promotion.] Ultrahuman Ring Air has been a lifesaver in tracking my sleep as I am not able to sleep with a watch on. The sleep, caffeine, and recovery insights are very useful in improving my quality of life each day. Also, the build quality and look is great!

[This review was collected as part of a promotion.] I’ve had my Ultrahuman ring for about 6 months. I’ve had several wearables over the year, and I feel like this one provides the most amount of information. I’ve had a few little glitchy issues, but they were quickly resolved. I’d definitely purchase again.

[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.] Really like the sleep tracking. Some of the other data is frivolous for the most of us, but could be insightful for the man with a PHD. Auto workout tracker kind of sucks, so just remember to start the workout manually.

[This review was collected as part of a promotion.] I was sleeping 7–8 hours most nights, but waking up feeling like I hadn’t slept at all. I’d scroll through sleep tips online, try magnesium, meditation, no screens before bed—you name it. Nothing really stuck, because I didn’t know what was actually going wrong. This ring changed that. It didn’t magically fix my sleep overnight, but it finally gave me a way to see what’s happening while I’m asleep. Turns out I wasn’t getting enough deep sleep, and my recovery scores were way off after high-stress days, even if I hadn’t worked out. The HRV data, resting heart rate, even skin temperature started to paint a fuller picture of what my body was going through. I also started noticing how my sleep improved when I ate earlier, skipped alcohol, or took a proper wind-down routine seriously. Before, it all felt like guessing. Now it feels like learning. The ring itself is great—super light, looks good, and I barely feel it at night, which is huge. I didn’t want another thing buzzing on my wrist. Honestly, I bought this ring because I was tired of being tired lol. But it makes a huge difference in my life.

I bought this in March I believe, and I really enjoyed it at first, but once I got an idea of what my results were going to be, I ended up not checking them any more. I don’t find the battery lasts that long, maybe a day and half to two days. I do get compliments on the way it looks, but as for a smart ring, I tend to lean more towards using my smart watch.
