This software can access Digital Black Boards (DSBs). It is optimized for Alexander-von-Humboldt-Gymnasium, but you can access other boards using the Reauthenticate button.
Use it as a replacement for the proprietary DSBmobile app. It loads a lot faster and doesn't make you click any buttons before you can see your plan.
*Displays entries in a nice, native list which you can filter (from Android 4.4, supported systems only)
