It worked for a month or two and now it won't charge or turn on. The app and instruction are basic and in Chinese (literally). I'm not a fan now....was when I got it, get a fit bit....it's much easier.
I was excited to get this item until it arrived. it came in an envelope with the bracelet, cord and instructions. the problem was the instructions were in chinese! I have no idea how to use it and will be returning.
