Timetable

This is an improved version of the app from ulan17 .
With this app you can manage your timetable, your homework, exams, teachers or notes.
The app also automatically switches your phone to do-not-disturb mode during classes and back again afterwards.
In addition, it always shows you a notification with your next subject.

Some other features I added:

• New Notifications (also about the current lesson)
• Weekly View
• Automatically turn on/off Do-Not-Disturb
• Dark mode
• Backup/Restore
• Shortcuts
• Splash Screen
• And some onClick Intents, e.g. If you click the phone number in the teacher-activity the phone app will be opened
• Some more little ui changes
