My Class Schedule (no ads) My Class Schedule (no ads)

the author of this app says:

My Class Schedule is a nice and useful timetable app for all students and pupils. After you add all your courses, the time at which they take place and some useful additional information (teacher, room, ...), the app shows your timetable in a day- and weekview. Moreover, for each course you can add the marks you received so that the app can calculate your average.
The newest version allows you to save homework for your courses.

Note: this is the ad-free version that includes some bigger widgets. If you just want to try this app or have no problem with ads, there is a free version available here:
