FAQ and troubleshooting
Quick answers to common questions and fixes for the things people run into most. If you don't see your issue here, the other guide pages go deeper on each feature.
Scheduling
Why did a student end up "unscheduled"?
Their availability didn't overlap your working hours, or every slot that would fit was already taken. After you generate, unscheduled students appear in a banner with the exact reason. Tap it to widen their availability, adjust your hours, or make room — then they'll slot in.
A lesson won't fit anywhere — what can I do?
Add another availability time slot for that student, extend your working hours on a day they're free, or shorten another lesson. Even small changes often open up a slot.
Does regenerating erase my hand edits?
Yes — Regenerate rebuilds the whole timetable from scratch. For changes you want to keep, edit lessons and breaks directly instead of regenerating.
Can I move a lesson myself?
Long-press and drag it to a new time (a Pro feature). Tapping a lesson to edit it is free.
Reading the timetable
The day columns are tiny on my phone.
Set Days shown in schedule to 3, 4, or 5 in Settings — you'll get wider columns and can swipe sideways for the rest. You can also pinch to zoom.
Can I change the lesson colours?
Lessons are colour-coded by activity. Tap the palette button on a schedule to override any activity's colour.
Importing and exporting
My spreadsheet columns weren't recognised.
If the app can't detect your day columns, it asks you to map them — and remembers your choice next time. Day headers are recognised in English, Norwegian, Swedish, Danish, German, French, Spanish, and Finnish.
Why is there a footer on my exported PDF?
Free PDF and print exports carry a small "Made with Schedule My Lessons" footer. Spreadsheet exports (Excel, CSV, Google Sheets) are always clean, and Pro removes the footer everywhere.
Is there a limit on how many times I can export?
No — exports are unlimited on every plan.
Account, privacy, and devices
Do I need an account?
No. There's no sign-up and no login — the app works fully offline.
Is my student data private?
Yes. Everything stays on your device; it's never uploaded, and we never see it. See Privacy & your data.
Is there an Android version?
Not yet — Schedule My Lessons is iOS only for now.
Does it work on iPad or Mac?
Yes. It runs on both iPhone and iPad, and on Apple Silicon Macs (M1 and later) you can run the iPad app right on your desktop from the Mac App Store.
I reinstalled the app — is my data gone?
Data lives on the device, so a reinstall can clear it. If you're on Pro, restore from a backup; and tap Restore Purchases to bring Pro back.
Undo
I made a change by mistake.
Most actions — deleting a student or schedule, imports, edits, drag moves, break changes — show an Undo option right after. One tap puts it back.
