Does not work as expected

It supposed to keep track of my steps, well it doesn't. Matter of fact it's got a mind of it's own, it reads a pulse of 75 even when I'm not wearing it, but no steps tracking or calories burned. Yes I downloaded the app and it connected and I tested the connection by placing a call through my phone. I played with it for a few hours and not one step was tracked. Needless to say I am returning it and looking for something better
