aSc Timetables vs GC Education Analytics K–12 Master Scheduler

aSc Timetables creates school schedules from requirements such as room and teacher constraints, student groups, and events. Its automatic generator evaluates more than 5,000,000 possibilities when building a timetable, and the system can detect conflicts. An AI panel can advise on timetable changes and, if permitted, edit timetable data. The substitution feature suggests cover teachers and records updates in class registers and calendars. Schools can share timetables and relevant substitution updates with teachers, students, and parents. The class register reflects schedule, substitution, and event changes, and supports recording lesson topics and attendance. Room bookings and school events can also appear in timetables and attendees’ class registers. The online version needs no installation and supports simultaneous work by multiple users; the Windows PC application works offline, with data transferable between versions. The unlimited free trial includes paid-version functions except export, and printouts carry a watermark. It has no free plan and lists Android, iOS, Linux, macOS, web, and Windows support.

GC Education Analytics K–12 Master Scheduler is a browser-based tool for building and refining master schedules, from elementary cohorts to high school block schedules. It supports elementary, middle, high, K–8, and 6–12 configurations. Scheduling models include self-contained, departmentalized, partner/platooning, split-band, traditional daily, A/B block, 4x4 semester, trimester, team-based, modified block, rotating drop, and multiple-variant schedules. Users can place sections by cohort and automatically generate elementary Art, Music, and PE rotations for homerooms. Constraints include teacher-period locks, unavailable times, room requirements, and course priorities. Real-time conflict counts and placement logs show where sections landed or why placement was not possible. Teachers and courses can be imported from CSV, and schedules exported as CSV for an SIS or printing. The scheduler runs in the browser without accounts or servers, keeps school data on the user’s machine, and saves work in browser IndexedDB. It uses a background Web Worker and offers teacher, room, and master-grid review views. The page describes it as a free beta with no sign-up, installation, or cost.
