Attending Staszic 1st High School in Lublin? This app will show you exactly the same timetable as what you can find on the school website - except it will do so even when you're offline! Just update it like any other app and you're good to go!
And if you're by any chance online at the moment of selecting the class, the app will also try to fetch the most recent sudden-teacher-changes(tm) and highlight the hours they affect! Yay!
If you'd rather get a timetable of another school that uses Vulcan-generated timetables, or you're not the type to dig 90s visual style, check out this gem by our dear friend.
