From the developer:
SchoolOrganizer is an application that makes your school life easier. With this tool, you can manage more than one timetable at the same time. It offers support for mixed lesson lengths (single and double). You are provided with two different timetables for even and odd weeks. The tool automatically adds homework for the current lesson based on the timetable. You can add exam date, time, place, and notes to the iOS calendar.
