Migration steps
1
Export from TickTick
Exporting your tasks under Settings → Backup gives you list, due date, and recurrence information.
2
Lists = lists
Map TickTick lists to Noti lists and tags to tags.
3
Import into Noti
Due dates become to-do deadlines, and priorities come in as importance markers.
4
Recreate recurring tasks
Writing something like "매주 월요일" in natural language recreates it as a recurring to-do.
Sync. After migrating, you manage events, notes, and alarms together in one app.
Frequently asked questions
Do Pomodoro records carry over?
Pomodoro and habit data are not transferred. The migration focuses on events, to-dos, and notes.
Is Korean recognition better?
It recognizes Korean time expressions like "다음주 화 3시" on the device first, so it is strong with Korean.
