From the developer:
ClassTime includes a timetable, task and file manager in one app. This utility reminds you of classes and tasks along with keeping your notes, lectures, class recordings, PDFs and images in one place. Beautiful widgets show your upcoming classes and pending tasks. Widgets are available in small, medium and large sizes. You can create a class or task directly from the medium or large size widget.
