Not worth the glitches

This app requires you to manually log out and back in every time you want to sync. And each time you log in, it defaults all the data options to sync - so if there is anything you do not want syncd (friends, for example, since there is no relevant data in Health connected to friends on Fitbit), you have to uncheck that box every time you manually log out and back in. Do yourself a favor and skip this app.
