Classgrid: Class Timetable

Classgrid is a weekly class timetable for high school and university. Pick a subject, drag down the grid, and the class is in. Your week is the home screen, with a red line at the current time and a card showing the class you are in now or the next one. Reminders arrive before each class. No account, no ads, works offline. • Paint classes in: choose a subject chip, then drag down an empty slot. A tap adds a class of the usual length, and every change can be undone • Unlimited subjects and classes, each with its own room, teacher, colour, type (lecture, lab, seminar) and different times on different days • Week A / Week B and other rotations of up to 4 weeks, plus cancelled days, holidays and one-off classes on a single date • Week and Today views: a timeline of today with the breaks between classes • Class reminders 0 to 30 minutes before each class, with exact-alarm support and a fallback. An optional evening reminder shows tomorrow's first class • Reminder diagnostics show notification permission, exact-alarm permission, battery optimization and the next scheduled reminder • Home-screen widgets: now and next, today's timeline, or this week's grid • Share the week as an image, back up and restore everything as a JSON file, and archive a past semester instead of deleting it • Included without Pro: one timetable with unlimited classes, rotations, reminders, one widget, image sharing, dark mode and backup • Pro adds multiple timetables, lock-screen wallpaper and PDF export without the watermark, unlimited widgets with six themes, attendance tracking, exam countdowns and alternate app icons • Pro is a one-time purchase, not a subscription, or pick the monthly plan with a 7-day trial • Your timetable stays on this device
