Basically useless
The app is pretty much useless and so is the TW64 activity tracker. It doesnt fit average women at 24.2 cm, its much too large. It doesnt track sleep at all like it claims. I had to use the app to restart the device every day because it would revert to the previous days step count. I ended up buying a TW64S, which has its own problems and uses a different app. If you cant afford a Fitbit and you think these cheap Chinese versions are at all comparable, forget it. They arent.
