ULTRAHUMAN Ring AIR - Sleep & Fitness Tracker, Smart Ring for Women & Men, No App Fee for Standard Features

⭐️⭐️⭐️⭐️⭐️ 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!

Loving the Ultrahuman AIR ring. Good battery life (3-4 days depending on your activity) and very functional app which gives you all the details (sleep, stress monitor, steps, HRV and skin temperature, etc.) you will look for in a smart ring.Really like the caffeine window power plug in the app along with the stress rhythm view. Great product and would highly commend to anyone looking for a smart ring. The no-subscription model makes this an even better proposition than the Oura ring.

SO FAR SO GOOD STILL GETTING USED TO THE APP. IT HAS A LOT OF INFORMATION AND APPEARS TO TRACK MY IWATCH VERY CLOSELY. ALTHOUGH NOT CHEAP IT IS AS GOOD AS ANY OTHER RINGS ON THE MARKET BUT WITH NO SUBSCRIPTION. GETTING THE SIZING KIT WAS A MUST AND I FOLLOWED THE ADVICE OF WEARING DIFFERENT SIZES ON DIFFERENT FINGERS BEFORE I CHOSE MY RIGHT HAND RING FINGER. UNFORTUNATELY THE STATED BATTERY LIFE OF 4-6 DAYS IS UNOBTAINABLE, I’M LUCKY IF I GET 3.5 DAYS IN BETWEEN CHARGES, HENCE 4 STARS BUT STILL PLEASED WITH MY RAW TITANIUM CHOICE.

Occasionally synced with Strava then stopped, doesn’t sync with Garmin and very poor response to resolve. It appears to monitor sleep but that’s about it. Not what I expected.UPDATE. I’ve now been told (by the help line) Ultrahuman does not sync with Strava. Very poor experience so far.

It's thinner than the Oura, has no subscription, provides basically the same data, AND is actively being updated. They are constantly bringing new things to the app, improving the look, settings etc. I wish I was blessed with thin fingers but I have not been, and after trying two other rings, I just felt like they were just enhancing how my fingers looked! Ultrahuman actually looks like a normal ring, it's just that little bit thinner, so it's been fantastic for me.It takes a while to calibrate, which would be the same with any of the smart rings, and absolutely sometimes tracks incorrect information - but I have an Apple Watch, Whoop and an old Oura ring, and they all do the same thing. If i'm watching TV for hours it thinks i've had a nap - which is clearly down to my laziness, not their tracking!Honestly, I think it's great, came in about 14 hours, and the company is suddenly getting VERY popular, so I think there is probably a mad dash internally to increase production and customer support. They've been great to me so far.

This is much better than a smart watch for wearing in bed to get all the readings for a healthy sleep and more. I forget Im wearing it. It is also accurate at counting steps and all the other readings. The charge lasts for around 5 days as stated and it hasa free lifetime subscription.The only bad thing, and it's a biggie is the sizing. The sizing rings are inaccurate, I sized mine for my index finger and after wearing the official sizing ring for two days and nights decided my size is 12, but after the ring arrived it didn't fit so I have it on my ring finger, even then when my hands get warm the ring feels tight. I might have to ructantly send it back. That's why only four stars.This is an edit.I bought this ring because it came subscription free. It does to a certain extent, but after owning it for a couple of months or so, the manufacturers of this ring have now added items that need paying for monthly.Now you don't have to buy them a the ring works fine, but if you want everything this ring can monitor then it's not completely subscription free, if this was not out of the 1 month change of mind time I would send it back.This would be the best value for money but not anymore. I am now knocking several stars off for not telling the whole truth about subscription free. Shame on you ultra human.
