Classnote is a school scheduler app that is perfect for students who want a simple and easy-to-use application. It allows you to manage your timetable and assignments with ease. The app is based on Material Design, which is a new design language developed by Google. This makes Classnote a well-organized and user-friendly app that offers convenience that other school scheduler apps lack.

The app is available on smartphones and tablets with Android 5.0 and newer versions, as well as Android Wear with Android 5.0 and newer versions. The app is currently localized in English and Japanese.
