Rozklad24 is a free, browser-based timetable platform for Ukrainian schools, lyceums, vocational schools and colleges. AI import turns the timetable a school already has (Excel, PDF or a photo of a paper schedule) into structured data, confirmed by a person before saving. The timetable builder covers teaching load, automatic weekly scheduling without gaps, checks against Ukrainian sanitary rules, multiple bell grids, subgroups and streams. When a teacher is absent, the app suggests colleagues who are actually free and produces the substitution order and paid-hours log. Built for wartime: air-raid lesson tracking and shortened-day bell grids. Students, parents and teachers open the live schedule from any phone via a permanent link or QR code, with no app or login. Print-ready timetables, Excel export and the teacher tariff list under Ukrainian Instruction No. 102. Free for schools and colleges.
