Why casual teachers need a different kind of schedule app

Most teacher planning apps assume you work at the same school, with the same timetable, every single day. Casual and supply teachers don’t work that way. Your schedule changes week to week, you might cover two or three schools in a fortnight, and you need something that’s fast to update and easy to access on any device.

Generic calendar apps (Google Calendar, Apple Calendar) can sort of work, but they don’t understand teacher terminology, have no concept of class groups or marking, and aren’t built for the way a casual teacher thinks about their week.

Teacher Task Manager is a flexible teacher schedule organiser that works just as well for a teacher covering one day a week as it does for a full-time HOD. Set up your timetable, add tasks as work comes in, and access everything offline from your phone.

Features that work for casual and supply teachers

Flexible enough to adapt to any schedule, simple enough to set up in minutes.

Flexible timetable

Set up your timetable to match whatever you’re covering, and update it whenever your placement changes. No rigid structure that assumes you teach the same classes every week.

A private scratchpad for lesson notes, class observations and reminders. Captured instantly, available offline, never lost between schools.
