I’ve ditched paper agendas long time ago, probably around 2nd year of high school, in favor of my first smartphone. To organize my student life I’ve always had to use several different apps (Google Calendar, Google Keep, Dropbox, Note, ecc…). It would be really cool to be able to integrate all these things into one app, that would work as a personal assistant. It would keep track of your courses and your progress, so you always know on which problem sheet you have to work and what you still have to study. The app would also work as a centralized storage for all your course materials (ebooks, pdfs, problem sheets, flashcards). Search functionality could be integrated as well to allow students to find new content from other students, TA or professors. Think of it as a centralized application for course management, both for students and professors. I imagine that something similar would not only improve the life of students but also give important feedback to professors and TA, since they would have access to the progress history of the subscribed students.
