Timewizer

Timewizer is a timetable maker for a single school. Enter your teachers, classes,
rooms and lessons, and Timewizer places every lesson so that nobody is in two
places at once. It works fully offline, with no account or login. Each school is
one file you can save, copy and open again.

Features: morning and afternoon shifts with their own bell times, teacher limits
and time off, rooms, double periods, lessons that must happen at the same time,
import from Excel or CSV, checks before building, drag and drop editing, and
printing or exporting to PDF, pictures, Excel and CSV.
