I tried to sync my data but it was not successful, what should I do ?

First, press the syncing button on the top right hand of the mobile app

Then, make sure ZeFit display in turned on to initiate the Bluetooth connection and ensure successful synchronization of data


If you still experience some problems:

- Make sure you have Wifi / 3G network
