It is possible to have your calendar in SpinOffice in sync with your mobile devices of Apple (iPhone, iPad and Mac) and Android.
Go to menu option Administration -> Personal settings -> Synchronization and enable the sync. Instantly a CalDAV-account is created and the manual how to configure this account on your Apple (iPhone, iPad and Mac) and Android device is sent to you by email. The calendar will appear in the Calendar application of the device. The sync works both ways, thus between SpinOffice <-> devices.
