Perfect Fit, Incredible Battery, Sleep Insights The ulterhuman smart Ring fits perfectly and is incredibly comfortable to wear all day and night. The battery life is outstanding. What truly sets it apart are the detailed insights it provides on my sleep patterns and overall sleep health. It’s helped me understand and improve my sleep in ways I didn’t think possible. Highly recommended for anyone looking to track their health with style and ease!

[This review was collected as part of a promotion.] The Ultrahuman Ring Air offers excellent health and fitness tracking as well as accurate sleep monitoring. It is compatible with a variety of devices and stands out for being a lightweight, comfortable ring. Overall, its accuracy is impressive and the system is very user-friendly

[This review was collected as part of a promotion.] I bought this ring in November and overall it’s fine, but I don’t think it’s super accurate. If I charge it overnight, it will still say that I slept and gave me a sleep score but I wasn’t wearing it. This has happened multiple times. It’s nice to wear and not bulky on uncomfy. Also I think the goals/metrics are mostly for walking, I don’t think it tracks other activity well. Also my charge will only last a day if I try and log any activity.

[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 bought my ring a couple months ago now & while I love it (the look, the functionality, the ease of using the app), I have had my fair share of connectivity issues. My partner bought his ring at roughly the same time and has had none of these issues so it’s definitely luck of the draw! I am a little disappointed with my ring on this basis, that it can be so expensive & still so unreliable. Buy with caution // a pinch of salt, for sure.

I’ve been using the Ultrahuman Ring Air for 3 months now and I’m hooked. Having previously used the Apple Watch, I found myself abandoning it after a while due to the constant need to charge it. In contrast, the Ring Air lasts 2–3 days on a single charge, powers up quickly, and is far less intrusive — no sweaty wrists or discomfort. The ring is light, comfortable, and effortlessly fits into my daily routine. Every morning, the first thing I do is check my sleep score on the app — it’s intuitive, detailed, and helps me understand where my sleep might’ve fallen short. The health insights are practical and motivating. Overall, it’s a sleek, smart, and reliable companion for anyone serious about improving their health without the fuss of a bulky wearable.

[This review was collected as part of a promotion.] Been using the Ring Air size 10 for more than a month now and the ring provides a substantial insight into the health parameters of the day. The app is concise and informative with all the necessary information right front and centre leading to an enjoyable experience while using the app. I particularly love the caffeine window and the sleep score information, both of which have greatly influenced by actions throughout the day to get the best possible sleep and rest required. The only thing that maybe improved in the long run is the battery life. Currently, on a full charge, the ring lasts for about 4 days.

[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.
