[This review was collected as part of a promotion.] It's super comfortable to wear. Nice accessory to wear. It's helped me to get better rest by managing my caffeine intake. Helped me to get better rest by going to bed earlier as it was showing me my sleep patterns.

[This review was collected as part of a promotion.] I wrote this as my review: Love the app for the ring. I've gained good insights into what affects my sleep for better or worse. The insights from the ring are much, much more in depth than I initially thought before I bought the ring. I had learned that while my sleep was good, my "morning alertness" was a big cause of why I felt so tired, so I've made major changes to stop checking my phone first thing in the morning and get moving instead. I knocked off one star mostly for battery life -- wish it were better. Other than that, I've stopped wearing my fitness watch in favour of the ring for its small form factor and detailed tracking.

[This review was collected as part of a promotion.] i bought this nearly 2 months ago, i love how its always updating with new plugs. the battery does not last at all especially if you workout everyday. the ring doesnt always connect to the app, sometimes theres too much info and its quite scary when it shows you your brain age etc

[This review was collected as part of a promotion.] The ring is amazing to use, best wearable possible. Sleep tracking is what I use most. Then the caffeine window. App is beautifully designed and has a lot of information. Would recommend to anyone who is considering.

[This review was collected as part of a promotion.] I’m absolutely impressed with this smart ring! It’s sleek, lightweight, and incredibly comfortable to wear all day. The tracking accuracy for sleep, heart rate, and activity is spot-on, and the battery life is excellent. I love how discreet it looks while still giving me valuable health insights. Syncing with the app is smooth and user-friendly. Totally worth the investment – highly recommend it for anyone who wants smart features in a stylish form!

I bought the ring about a month and a half ago, and I`ll admit I was a bit skeptical at the time of purchase. But I have to say, I´ve been very positively surprised. It´s not only useful to wear, but it´s also genuinely interesting to follow the data it provides. I even find myself trying to improve my metrics, which is a great thing-and something entirely thanks to the ring. The bottom line is: my skepticism was completely unnecessary.

[This review was collected as part of a promotion.] The ring itself is good and looks nice. The issue with the product is the partnered App, as it is very unstable. There are times when it syncs well, there are times that it wont and requires constant restart. I wish they can embed auto sync.

[This review was collected as part of a promotion.] I’ve been testing the Ultrahuman Ring Air, and it’s quickly becoming a valuable tool for monitoring recovery, sleep, and overall readiness. The design is sleek and comfortable, making it easy to wear around the clock without disrupting daily activity or training sessions. What stands out most is the depth of insight provided. HRV tracking, sleep stage analysis, and metabolic health markers are presented in a way that’s both actionable and easy to interpret. The seamless integration with Ultrahuman’s ecosystem adds another layer, allowing for a more holistic approach to athlete monitoring and personal performance optimization. For anyone serious about understanding their body’s response to stress, recovery, and training load, the Ultrahuman Ring Air offers a level of precision and usability that’s hard to match. I’m excited to continue exploring how this can support athletes at the elite level.

[This review was collected as part of a promotion.] I bought this ring around 2 months ago. I am definitely satisfied with the software and functions of the ring. What I am not really satisfied with is the physical aspects of the ring. Its really chunky and it leaves marks on fingers after wearing it for too long. I have to change the ring from one hand to other every day.

I’m really happy with my Ultra Human Air Ring and wear it every day. It has given me a lot more insight into my sleep, I now have a better understanding of my overall sleep quantity and the different sleep phases. Additionally, the ring helps me track my stress levels and I can visually see when I need to take it easy and slow down, which is really useful. I’ve only just started tracking my cycle, so I’m still unsure about its accuracy, but the data looks clear and organized. The ring is comfortable to wear. It’s a bit discolored now, which I find a little disappointing, but I understand since I wear it all the time. Overall, I’m really happy with it and would definitely recommend it to anyone looking to gain more insight into their lifestyle. The battery life is great too!
