[This review was collected as part of a promotion.] I have been a customer since Ring R1 for the ease of use for health tracking (especially sleep), and when they launched the Ring Air it just got even better with all the useful functionalities in an even smaller form factor. Just crazy how tech has evolved.

[This review was collected as part of a promotion.] The battery needs to be charged more often than expected unless I turn it down to only track the minimal (sleep etc). Maybe it being in the sauna drains the battery or when I used to click a functional workout real time maybe that is also draining the battery. Lastly, I have the silver, and there are lots of hairline scratches on it and it feels like plastic on top. Maybe there can be other cooler finishes like textured to help disguise the scratch potential? Otherwise cool and lots of info and options.

[This review was collected as part of a promotion.] I’ve been using the ring for almost a year now and have really been enjoying the sleep tracking. It’s awesome that power plugs are being extended from the current options and are constantly being improved.

[This review was collected as part of a promotion.] I am happy with the insights this ring has given me in regards to sleep quality/timing, stress levels. It is light on my finger and most of the time I hardly notice it is there. I did have an issue with my first ring but was quickly sent a replacement. Unfortunately I have had relatively consistent issues with battery life even after troubleshooting in the app multiple times and using Chill mode (less battery utilization). For example, I will start the night with near full charge and be down to <30% by awaking in the AM. I wonder if some of the battery issues are firmware related as I had relatively good life for several months but then had an acute decrease in battery life in the past 1-2 months.

[This review was collected as part of a promotion.] So far I love my ring! It’s been a great insight to my health and my fitness journey. The only thing I’ve noticed is my battery doesn’t hold as well as it did when I first got it and it’s only been a few months. I don’t mind because I charge my Apple Watch every night so I am in the habit of plugging in all devices and it charges quick. But I have noticed a big change in it last 5 days to only lasting 2 now, and it’s always in “chill mode”

[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.

I have had the ring for about 5 months now, and my experience has been nothing short of excellent! It has become a crucial part of my health and wellness journey, and I am amazed by the helpful insights and recommendations it provides to improve my lifestyle and routine. Not to forget, the aesthetic appeal is an absolute bonus!

[This review was collected as part of a promotion.] Love this product - love the colour options and the fact that this is super insightful and that it’s so light. I feel really good about the metrics it’s given me over the last month as well and they’re helping me move more and rest better

[This review was collected as part of a promotion.] I received this a few months ago and I’ve enjoyed using the ring so far. Some of its features are extremely accurate as it gets to know your body. I’m looking forward to more features in the future!

It’s pretty great and I haven’t thought of the Apple Watch at all since owning the ring. It’s tough and durable for working out and tracks my life accurately. Sometimes it does lose data or get disconnected while working out which can be frustrating.
