I really love the Ultrahuman ring and the data it collects. I like that their is no subscription but you can add particular information if you'd like. My only thing is I wish it was a thinner band.

I got my ring and the end of last year (2025) It's been 4 months with me using it daily and now it's not holding a charge for more then a day and it's not tracking like it used to.
