ULTRAHUMAN Ring AIR – Sleep and Fitness Tracker, Smart Ring for Men and Women, No app fee for standard features, Up to 6 days battery life (Bionic Gold, 12)

⭐️⭐️⭐️⭐️⭐️ Game-Changing for Biohackers, Fitness, and Recovery!I’ve used nearly every fitness wearable out there, but the Ultrahuman Ring AIR is hands-down the best for anyone serious about tracking health, recovery, and performance.What sets this ring apart is the depth and clarity of its data. It gives me real-time feedback on HRV, sleep quality, skin temperature, and activity in a way that’s actually actionable. Since wearing the ring, I’ve learned exactly how my lifestyle (from hiking and strength training to my daily walks and even supplement timing!) affects my sleep and recovery.The sleep tracking is next-level. The ring doesn’t just tell me how long I slept—it breaks down deep, REM, light sleep, restlessness, temperature changes, and even my body’s recovery rhythm. I was shocked at how accurately it picked up on changes after a heavy workout or even a late night out, and it’s helped me dial in everything from caffeine timing to my bedtime routine. Since using the ring, my sleep scores have improved, and I wake up genuinely refreshed.I love how seamlessly the ring fits into my daily life—it’s light, comfortable, and doesn’t need constant charging. The app is user-friendly, visually stunning, and gives personalized recommendations I actually want to follow.What really sold me is how the Ultrahuman ecosystem ties everything together. It’s not just about steps or calories—it’s about truly understanding your body’s readiness, recovery, and how to push for better results without burning out. It’s helped me break a fat-loss plateau, optimize my training, and finally get those deep, restorative sleep cycles that every biohacker dreams of.If you want to level up your health, perform at your best, and unlock a new level of self-awareness, the Ultrahuman Ring is a must-have. I’m obsessed—and I can’t wait to keep smashing my goals with it. Sleep mask or not, this ring has already improved my life. Highly recommended!

i think the Ring Air is just fabulous. Excellent battery life that easily lasts 5 days. I don't really have to test it because I pop it on the charger when showering and that pretty much keeps it topped up. The Ring Air is very comfortable but I have developed a habit of sliding it half off to check it's positioned correctly and then sliding it back on. I wear mine on the ring finger of my right hand and find it to bee a good fit for me. The Ring Air and its competitors are all thicker than most rings and this can cause discomfort when wearing it on the middle or ring finger because they have fingers on either side. I can see how wearing it on the index finger might be most comfortable but after wearing the sizing kit on this finger for a day, it felt like it was constantly in the way or getting bashed on things. I've had my Astral Black Ring Air now for two months and it has yet to show any signs of wear.Accuracy seems pretty good but I've found the steps under count by about 5% compared to my smartwatch and the SpO2 never seems to go under 99% which for me I know is not right. SpO2 is still a beta feature though so I hope this gets more accurate. Sorry Ultrahuman but you lost a star there.I love the app! It is excellent and provides great detail on your various stats and I like the nudges to remind me about movement and stimulant windows. I know the Oura gets better scores from a lot of people and I ordered both to compare. The Oura was just as comfortable to wear but everything about Ultrahuman's app was so much better and did not require £6 per month to use. I'm very pleased with my decision to go with the Ring Air.

I purchased the Ultrahuman Ring in June, 2024. Initially, the ring functioned as advertised, providing insights into my sleep patterns and activity levels. However, in January, 2025, it abruptly stopped generating meaningful data.Despite following all recommended troubleshooting steps—updating the app, reinstalling it, and performing multiple firmware updates—the issue persisted. I reached out to Ultrahuman's customer support, only to receive repetitive suggestions to update firmware and restart the app, which I had already done. My requests for a replacement under the warranty were met with delays and unhelpful responses. It's worth noting that other users have reported similar issues.Given the premium price point, I expected a reliable product and responsive customer service. Unfortunately, my experience has been far from satisfactory. I can no longer recommend the Ultrahuman Ring to others and advise potential buyers to consider alternative options.

I've had the ring for a week now.ProsThe ring is fairly slim, which is why I chose this product, and it looks good.The app gives a great deal of information and lots of instruction. Still going through it all as the data builds but very impressed so far.No subscriptionConsThe size 11 ring in the sizing kit fit perfectly. I wore it for a whole week before I ordered. Ring arrived and it is too big.HR is inaccurate. But this could be related to the point above.
