School Bell

School Bell turns your phone into a reliable, automatic bell system for a classroom, small school, or tutoring center — no extra hardware required. Set your lesson timetable once, and School Bell rings on schedule every active school day, exactly on time, using Android's exact-alarm system so it fires even if the phone is idle or in Doze mode. KEY FEATURES • Lesson-based schedule — enter each lesson's start and end time, and the bell rings for both automatically. • Choose your active days — Monday–Friday by default, or any combination of weekdays for a different schedule (e.g. a Saturday-only program). • Holidays and breaks — add date ranges where the bell stays silent even on an otherwise active day, so you don't have to remember to turn it off. • Repeats the bell sound — configure how many times the sound plays per ring, so it's heard clearly throughout the building. • Custom bell sound — use the built-in bell, or pick any sound or ringtone already on your device. • Adjustable volume — set the bell's playback volume independent of your phone's other volume settings. • Live status — the app always shows the current lesson, the next bell time, and a persistent notification confirming the schedule is running, with a one-tap Stop action. • Survives reboots — if the schedule was on before your phone restarted, School Bell automatically re-arms it. • Quiet notifications — optionally silence the heads-up alert and keep just the bell sound. PRIVACY School Bell works entirely offline. It has no ads, no analytics, no account sign-in, and no data ever leaves your device. Whether you're running a single classroom or a whole school day, School Bell keeps the bell ringing on time so you don't have to watch the clock.
