WHAT FITBIT WATCH IS COMPATIBLE BECAUSE THERE IS DIFFERENT ONES OF FITBIT WATCHES
Fayette County Kentucky
I am not certain I understand the question. What are you trying to sync a Fitbit watch with? Best, Diana
If it is the FitBlue program, any FitBit device should work. The difference in the FitBit devices is the data it collects. You will only be required to document steps with FitBlue but the additional cardio, etc. info on more advanced devices is beneficial for monitoring your heath.
