Syncbit will sync your data from Fitbit API to Health App on your iPhone! Simple like this!
You walk, run, exercise. Your Fitbit wristband is monitoring everything. But... Where is the data? Historical data? On Fitbit website? C'mon. You need this data on your iPhone Health App so you can review it, get more motivation, analyze and check your improvements.
Don't use Fitbit to generate useless data. You own all that data and it is important for you to improve!
