[This review was collected as part of a promotion.] I bough and used the ring for one year now. I liked the shape, battery life, and data collected. U have difficulty with: - the way results presented in the app. it is somehow complicated. The font size in the app is small and require reading glasses

[This review was collected as part of a promotion.] I bought it a few months ago. It works mostly like expected but I have some issues. When working out it takes forever to connect when starting the work out and ending it. During the night the app sometimes doesn’t work through the night and my alarm doesn’t go off. However, the menstrual cycle prediction is very good.

[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.

[This review was collected as part of a promotion.] This was a great purchase! Thanks to the caffeine window feature, I stopped drinking coffee right after waking up and started feeling more energized during the day. It also motivates me to stay more active during the day, and offers many interesting insights into my health. I really like that they are rolling out new features all the time!

[This review was collected as part of a promotion.] Since becoming a first-time mom, managing my sleep has been a challenge — but the Ultrahuman Ring has made a huge difference. It’s so light and comfortable I forget I’m wearing it, and it gives me super useful insights to help prioritize rest without any extra effort.

[This review was collected as part of a promotion.] After tons of research, I settled on the Ultrahuman Ring AIR, and I'm glad I did. The app is so very user friendly and I absolutely love how I can dial in which notifications I can receive. I compared the ring for the first few weeks with another watch-based tracker, and the results were identical. I absolutely love that it catches my activity level - even naps! - without me always having to enter data! Very accurate. And the ring is so comfortable to wear!

[This review was collected as part of a promotion.] I’ve been using the Ultrahuman Ring AIR for a few weeks now, and I’m genuinely impressed. It’s sleek, lightweight (you forget you’re even wearing it), and packed with features that offer deep insights into both fitness and recovery. What I love: Form Factor: The ring design is a huge win. It's more subtle than a smartwatch and comfortable enough to wear 24/7—even while sleeping or working out. Sleep and Recovery Insights: The recovery score and sleep tracking are incredibly accurate. It not only tells me how long I slept, but how restorative that sleep was, which helps guide how hard I should push myself the next day. Metabolic Health Tracking: Paired with the Ultrahuman app, the AIR ring gives great context around glucose variability and how your body responds to food, movement, and rest—especially if you're also using their M1 glucose monitor. Battery Life: Lasts around 4-6 days on a single charge. The charging case is also very convenient. Could be better: No live heart rate: It tracks HRV and resting heart rate well, but doesn’t give live heart rate data like some fitness trackers. Size availability: Sizing can be a bit tricky, so make sure to try the sizing kit before ordering your actual ring. Still evolving: Some features are still in beta or rolling out slowly. But the updates so far have been meaningful. Final Thoughts: The Ultrahuman Ring AIR feels like the future of health optimization. If you're into biohacking, performance training, or just want to better understand your body’s rhythms, it’s absolutely worth considering. It’s not just about data—it’s about making smarter daily decisions. Highly recommended.

[This review was collected as part of a promotion.] I really enjoy the Ultrahuman ring AIR! The in depth data results allows me to plan my health and life intentionally, whether I need to take a rest day or exercise harder, go to bed earlier or know what time to wake up etc. the information is amazing!

[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 bought the Ring AIR less than a year ago in December 2024 and I’ve been extremely satisfied and impressed with the insights available, especially sleep. However, in recent weeks, the battery life has absolutely diminished and I struggle to get through a single day without charging once or twice.
