This used to be just perfect for getting Fitbit data into health. Unfortunately iOS 9 wont let apps access health data with your phone locked, so it now only works with the phone unlocked, which means the auto-sync feature doesnt really work anymore.
Its frustrating because apple decided they didnt want something like this to work how we wanted it to anymore, but the app still syncs data manually just fine. So not five stars not because of any fault of the author, but just because it wont do what people want it to.
