Built around the calendar teachers actually use
Correct when the week is not.
Belfer treats the calendar model as the product. Day types, bell variants, sections, meetings, and lesson intent stay distinct so a change in one does not silently rewrite the others.
Bell times, independently
Keep the school-day identity separate from regular, delayed, assembly, testing, exam, and early-release bell variants.
Terms and sections
Plan across multiple terms and teaching sections, including repeated sections of the same course with their own meeting pace.
Exceptions without the scramble
Preview date-level schedule changes before applying them, then keep lesson intent connected to the right meeting.
Pacing you can see
Compare planned, taught, partial, skipped, canceled, and carried work while keeping repeated sections aligned.
Short lesson intent
Record an objective, agenda, materials link, homework, and an optional private note—enough for the day, without a document editor.
Made for the gaps between bells
Today first. The rest close at hand.
Belfer leads with what is happening now, what comes next, and what you planned. Week and course views add context on iPhone and iPad, while Home Screen and Lock Screen widgets keep the next useful detail visible.

Student-data-free by design
Your planner is not a student information system.
Belfer is designed for schedules, teaching sections, and concise lesson intent—not student names, grades, attendance, accommodations, rosters, or education records. Ordinary use works offline, with planner data stored on the device. There is no Belfer account, advertising, tracking, or developer analytics in the current implementation.
Optional private iCloud synchronization is designed into the app but is not configured for production. The complete policy explains what is implemented now and what must be reviewed before release.
