About Exercise Book
Exercise Book (Package Name: online.stoehr.blackboard) is developed by Robert Stöhr and the latest version of Digital exercise book 7.7 GrabCam Permission Fix was updated on September 30, 2026. Digital exercise book is in the category of Education. You can check all apps from the developer of Digital exercise book. Currently this app is for free. This app can be downloaded on Android 8.0+ on APKFab or Google Play. All APK/XAPK files on APKFab.com are original and 100% safe with fast download.
This app aims to enable digital exercise book management for school lessons. I started programming it many years ago because I couldn't find an app for my geometry lessons that allowed me to carry out constructions like in a school exercise book. The focus of the app is on creating exercise book entries, just as you would with an analogue exercise book and the usual utensils you have in your pencil case. Accordingly, there are no countless setting options that only distract and waste time. All exercise books are saved locally on the device and no usage data is collected so that the app can also be used in a school environment in compliance with data protection regulations. The app can be used free of charge without annoying adverts. Since 2025, however, it has also been possible to support the development of the app financially.
