[This review was collected as part of a promotion.] I have been using the ring for about a year now and I am very satisfied. I track my sleep cycles every day, I follow the caffeine window, I use it a lot when exercising. All the results are very clearly interpreted, I use several powerplugs. I would definitely buy it again.

[This review was collected as part of a promotion.] I’ve really enjoyed seeing these statistics, especially the sleep score. As a mom, I also love the “new parent” plug in that accounts for rest + mindfulness moments. As far as design goes, I love the look and after a few days of wearing, barely even notice I’m wearing the ring. Overall, would recommend!

[This review was collected as part of a promotion.] I got my wife an Oura ring. She wanted me to have a smart ring too and I picked the Ultrahuman because I hoped it would help monitor for a-fib and also because I didn't need a monthly subscription. It seems to track sleep as well as the Oura and costs less, so that's a win. Unfortunately, the a-fib detection wasn't available in the US yet. The caffeine window feature is nice, reminding me when to stop drinking caffeine and to delay in the morning.

[This review was collected as part of a promotion.] Bought this mainly for sleep tracking as hate Apple Watch in bed. The ring is light reliable and get 5-6 battery without worrying about it. On top of that I really like the app and the insight it provides on top of sleep tracking, If your on the fence about purchasing I would go ahead and do it

[This review was collected as part of a promotion.] Almost a full year with the RingAIR It was a toss up between your ring and the Oura ring and yours won the flip. I was looking for all the features the Ring AIR provides (not behind a subscription paywall) in a ring formfactor. Please keep those "free". I decided to go with the matte grey version. It got some wear on the metals edge but I like the way that looks. The rest of the build quality is great! My only criticism is the app's UI is very over stylized. I get the want to have a unique look and feel but the data gets lost in all the graphical elements.

[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 wearing the Ultrahuman Ring AIR in gold and it has completely changed the way I understand my body. It gives me incredibly accurate insights into how I sleep, when I need to rest, where I am in my menstrual cycle, and how well I am recovering physically and mentally. The amount of meaningful data this ring delivers is amazing. What really stands out is how clearly it presents everything, helping me make smarter choices about my health, energy, and daily rhythm. It feels like having a personal coach on my finger. The battery does need to be charged fairly often, but I usually do that while I take a shower. It fits easily into my routine and keeps the ring ready throughout the day. I honestly would not want to be without it anymore. If you are serious about understanding your body and making better lifestyle decisions, this ring is a game changer.

[This review was collected as part of a promotion.] The rings sleeptracking is working really well and helped me a lot in structuring my day. From caffeine windows and managing my circadian rhythm, the ring has really helped me improve my sleep quality and sleep hygene a lot. Wouldn't want to miss it ever again.

[This review was collected as part of a promotion.] I love this ring! One of my favorite features is the caffeine window and the sleep tracking. I’ve always wondered when i should be tapering off caffeine and what time is best to start getting to bed. If you’re looking to better your health habits, you won’t be disappointed.

[This review was collected as part of a promotion.] I bought my ring 3 months ago so I can say - it meet my expectations. I have the clear information about my sleep moreover there's a lot more comfortable to sleep than with watches. The ring provides useful tips throughout the day.
