The unofficial app for Hesse's education portal allows to use it with ease, instantly. Your school must support the "Mein Unterricht" tile.

Apart from "Mein Unterricht", the app also supports:
- Messages to and from teachers
- Your timetable
- Changes in your schedule
- Study groups
if your school has enabled each feature.

Please contact me about any issues you experience!

This app is open source and available on GitHub: https://github.com/koenidv/sph-planner
