I bought this ring in March of 2024 and it is now Aug of 2024 and I absolutely love my ring. I got it because I enjoy tracking my sleep and exercise but I can not sleep in my watch. The ring has been a great option I wear it all the time except to charge in the shower and I haven't had any issues. BUY THE RING!!

[This review was collected as part of a promotion.] I absolutely love this ring, it’s the best of its kind, although on an odd occasion it doesn’t record my sleep however it’s usually connected to an update which the do frequently to keep the ring up to date. It’s great for raising your awareness of good quality sleep and overall health.

[This review was collected as part of a promotion.] Fits snug and comfortable. Does not capture sleep well when I get up in the middle of the night and then return to bed. Also, data does not always capture when traveling especially out of the country. Otherwise a good product

[This review was collected as part of a promotion.] I’ve had my Ultrahuman Ring AIR for about 6 months now and it has changed my lifestyle completely around. I have never had a fitness tracking device so being able to get insight into my sleep and step count among many other metrics has changed my lifestyle completely around. I’m more aware of how many steps I should be taking each day, seeing how my sleep affects my recovery, and paying attention to my caffeine window has allowed me to be more alert throughout the day. I love my Ultrahuman Ring & I recommend it to anyone!

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring AIR for the past few weeks, and I can confidently say it's one of the most impressive health wearables I’ve ever tried. 💤 Sleep Tracking: Unmatched Accuracy The sleep insights are incredibly detailed — not just light/deep/REM stages, but also sleep efficiency, HRV, resting heart rate, and temperature deviation. I finally understood why I felt tired some mornings even after 8 hours of sleep. ❤️ HRV & Recovery Monitoring The Ring gives me daily Recovery Scores, factoring in my HRV, temperature, and sleep quality. This has helped me optimize my workouts, knowing when to push hard and when to rest. I’ve never felt more in tune with my body. 🔥 Movement & Metabolic Scores Ultrahuman doesn’t just track steps — it gives a holistic view of how much I’m moving and how it impacts my metabolism. Combined with smart nudges, I’ve naturally improved my daily habits without feeling pressured. 📱 Beautiful, Intuitive App The Ultrahuman app is beautifully designed, easy to navigate, and filled with actionable insights. I’ve used other platforms like Oura and Whoop, but Ultrahuman feels more modern, practical, and motivating. 🪶 Comfort & Battery The Ring AIR is super light, I forget I’m wearing it — even when sleeping or working out. Battery life easily lasts 4-5 days, and charging is fast and hassle-free. Ultrahuman Ring isn’t just another fitness tracker. It’s a real-time feedback loop for your body, health, and lifestyle. Whether you're an athlete, a biohacker, or just someone who wants to optimize energy, sleep, and stress, this ring is a no-brainer. Highly recommended. 10/10.

[This review was collected as part of a promotion.] I wish I bought this sooner! I've wanted a smart ring for a while and I am blown away by the insights I get every day from Ultrahuman. The notifications are amazing and I've made so many changes over the last couple of months to positively impact my health and my sleep. Seeing the data in real-time is SO encouraging! Especially with sleep-being able to see how certain supplements or eating after dinner impact my sleep is so empowering.

[This review was collected as part of a promotion.] I thought this ring primary because I did not want to use a smart watch… still wanted to track my sleep and other vital metrics..it works very well and provide all the important statistics and more… What are the best options without a subscription!

[This review was collected as part of a promotion.] Have had this ring for a little over 8 months. overall my experience with the ring has been good, there are a few features that I feel are missing from the app. Also the social jet lag feature has never worked for me. I think the app could use some enhancement for ease of use

[This review was collected as part of a promotion.] I am very happy with the features of this ring. My only small issue is the battery seems to die rather quickly. But overall great experience! The menstrual cycle/contraception tracker is super helpful.

[This review was collected as part of a promotion.] I bought my ring a couple of months ago, based on personal recommendations and reading reviews. I tested the template rings first, which is a great idea to ensure you pick the correct size and also the colour you prefer. Set up is simple and I was able to use it straight away. I’ve found that the step count numbers vary quite a lot from both my Apple Health and Fitbit phone tracking apps and also my Garmin watch. The counts are significantly lower than all the others. This may be because it is more accurate but it was very surprising, given the others were all at similar levels. I don’t find some of the app metrics overly useful as yet, and feel like the sleep score could be part of the overall dynamic recovery measures. The jet lag measure just displays the same info most of the time too. The caffeine metric is one I have been using a lot and find value in this one, which is good. Also not having to pay a subscription is a big benefit. Overall, I’m glad I’ve tried it but do think there is room to improve on a number of factors, to take it to the next level.
