If you want to manage more than one Vifit® Connect Activity Tracker on your PC/MAC there are two possibilities:
a) You start the VitaDock® software for PC/MAC and click the button on the bottom right which contains a chain as symbol to disconnect your current online account. The notification "Disconnect your Account? After disconnecting your data is not going to be synchronized from here..." appears and another person can now login/register to their VitaDock® Online account.
b) You set different user accounts on the operating system of your PC/MAC and manage the individual ViFit® Connect Activity Trackers on the concerned user accounts.
