Yep. Tried lots of places on the body, pockets, ankle. Same issue. I even made a necklace and tried it around my neck, still wrong. I had a Shine before and that was spot on. My next tracker will have GPS capabilities.
Misfit normally very good did u tell the app where it was on body ?
I have used one of these. My advice is to test the accuracy asap, mine was way off. It said am 8km run was 11k when it was on my wrist, and 10k when it was in my pocket. My other half has one and it's practically spot on. Unfortunately I couldn't find a way to calibrate it so it had to go. Ymmv.
