[This review was collected as part of a promotion.] I got my wife an Oura ring. She wanted me to have a smart ring too and I picked the Ultrahuman because I hoped it would help monitor for a-fib and also because I didn't need a monthly subscription. It seems to track sleep as well as the Oura and costs less, so that's a win. Unfortunately, the a-fib detection wasn't available in the US yet. The caffeine window feature is nice, reminding me when to stop drinking caffeine and to delay in the morning.

[This review was collected as part of a promotion.] Honestly, I love the Ring AIR. I received it as a Christmas gift from my husband and all the data output has been amazing; I love the tracking, all the types of data & insights, and the fact it replaces a handful of gadgets into a simplified app! Added bonus is the new additions coming all the time with fertility & cycle tracking, and how the insights play into my pregnancy with resting heart rate & sleep data. The only reason for a drop in the stars is because the battery life/capacity has greatly diminished in the months since I started using it (I received the ring in December, and have used it daily for the last seven months). While at first it lasted a few days at a time, now even in a lower "Chill" mode, I have to charge it multiple times per day to be sure I have enough battery power to track my sleep data overnight.

[This review was collected as part of a promotion.] I got it in March and already have the second replacement because it stopped connecting after a firmware update, so now I don’t update the firmware because I’m scared it will stop connecting again. But I am super happy with it when it is working

I am using the ultrahuman ring . Its a great product . Good built, the data and the insight dashboard is very clean and easily readable . I would be happy if I am able to customize my dashboard . For example . When I wake up, I want to see my sleep data first , cz the movement has not yet started. The app should automaticlly move the movement widget on top after it has recorded a certain steps . Another cool feature would be , top 3 metrics to focus on for next one month . there are lots of metric and not every time every day I will have all metric 100% or optimal , but lets say I am a runner (Which I am ), I would want to know top 3 (could be any number) metric to focus on to improve my running goal / recovery score from X to Y . Sort of personal coach or motivator

[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.] Ultrahuman Ring AIR is an excellent product that helps me track all my physical activities, and monitor my heartrate, HRV. I have been using it for last 6 months and with the increase in my cardio, the correlation i see in dropped heartrate is amazing. The caffeine window and circadian rhythm are such a great add on. The sleep scores are so accurate and i can always see how that score correlates to my mood and energy for the entire day.

[This review was collected as part of a promotion.] So glad I decided to invest in an Ultrahuman! I originally invested in it for its ability to seamlessly track my sleep without having to wear an uncomfortable watch to bed (that would also have to be charged at some point in a 24 hour window. Since then, I can honestly say that my ring has helped me recognize and transform habits from sleep to Vitamin D exposure to caffeine intake to morning rituals. Excited to see how Ultrahuman keeps evolving!
