The Configuration App
Tap on the Picture on the Picture Wall Calendar Widget or start the App from your App Drawer. There is only one Configuration for all Widgets but each Widget can show different Months in different Sizes.
Import free Calendar packages
There are several free Calendar Packages available for Download. These can be imported directly into the App if you tap the Links in your mobile Browser on the Device the App is installed.
You may also download them to your mobile Device and import them by sharing them from a File Explorer app to Picture Wall Calendar.
