Description

Unofficial app for students of the Zespół Szkół Elektronicznych (school of electronics) in Bydgoszcz, Poland. It reads the school's public websites directly - no login and no personal data collected. Works offline. Features

  • Daily and weekly timetable with substitutions applied; the current lesson shows the time left
  • Class groups: only the lessons you attend (languages, workshops, PE, religion)
  • Substitutions for your class and group, including cancelled lessons
  • Notifications about new substitutions (day, lesson, subject and teacher) and news, quiet hours
  • Notes for upcoming lessons with a reminder the day before or before the lesson
  • Lesson reminders with the room number
  • School news read in the app, with photos, search and favourites available offline
  • Home screen with the current or next lesson, breaks and substitutions
  • Widgets: Next lesson, Day plan, Substitutions, plus a quick settings tile
  • Departures from school: next public transport connections to a chosen stop, without GPS (optional)
  • Custom subject names and colours, light and dark theme, accent colour, wallpaper colours, app icon choice
The app's interface is in Polish. Not affiliated with the school or VULCAN. Inspired by Atom (iOS) by Kacper Górka. Free software under GNU GPL v3 or later.

What’s new (1.0.1)

New: live notifications (Settings → Notifications) count down to the break or the next lesson on school days, with what is on now and next.
New: school notices from the substitutions page (e.g. blood donation).
Next lesson widget: "in X min" at every size and the following lesson.
Opening the app refreshes substitutions at once; widgets change at the bell.
Lessons your class is freed from are no longer shown as ongoing.
Timetable and reminder fixes.
