ULTRAHUMANULTRAHUMAN Ring AIR – Sleep and Fitness Tracker, Smart Ring for Men and Women, No app fee for standard features, Up to 6 days battery life (Aster Black, 9)

⭐️⭐️⭐️⭐️⭐️ 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!

Blown away by this, very rare I write a review but I feel this deserved one.Ordered the sizing kit and 2 days later ordered the ring, I ordered size 10 and felt the ring itself was a tiny bit bigger which suited me perfectly.The battery life is amazing, I’m easily seeing 4+ days usage without any charge. Topping it up whilst in the shower keeps it going 24/7 for me personally.The app itself is brilliant and full of information, you can add in features which is great. I use a third party sleep tracker and this matches the ring statistics.I ordered this as I prefer a traditional watch over Smart watches and now I get best of both worlds.The connectivity between the app and ring is seamless, setting it up was extremely easy.Appears to be very durable, no scratches or marks despite some hard work whilst working.The gold colour is beautiful, doesn’t look cheap and looks professional.Great product, highly recommend and the best part? No subscriptions!

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.
