Teacher Time Keeper vs BellSync

Never lose track of what period it is, how much time is left, or when the bell rings next. Teacher Time Keeper is a live schedule and countdown app built specifically for teachers who deal with bell schedules, block periods, and rotating day cycles — on your iPhone, iPad, Mac, and Apple Watch. ROTATING SCHEDULES, HANDLED Set up the way your school actually runs: the same schedule every day, A/B alternating days, 3-, 4-, or 5-day rotations, a fully custom rotating cycle, or a different schedule per day of the week. Assign school days, holidays, and one-off date overrides (early release, assemblies, delayed starts) without breaking your rotation count. LIVE COUNTDOWN, EVERYWHERE A big, glanceable countdown shows exactly how much time is left in the current period — right on your Today screen, in a Home Screen or desktop widget, and on your Apple Watch with complications for every watch face style. KNOW BEFORE THE BELL DOES Get a notification before a class is about to end, so you have time to wrap up the lesson, collect materials, and be ready to transition — instead of getting caught mid-sentence when the bell rings. Set alerts before or after a period starts, before or after it ends, or right at the moment it starts or ends — six trigger types you can mix and match per rule, so you get exactly the heads-up you need for every transition, all day long. BUILT AROUND YOUR SCHOOL'S ACTUAL CALENDAR Define your school year, mark non-school days in bulk, and fine-tune a bell-time adjustment if your school's physical bell rings a few seconds off from the clock. A full scrolling calendar view shows every day's resolved schedule at a glance. SHARE YOUR SETUP Built your rotation once? Export it and send it to a colleague at the same school so they can import your exact schedule, calendar, and rotation pattern instead of building it from scratch. PRIVATE BY DESIGN Your schedule data syncs across your own devices via your private iCloud account. There's no login, no ads, no tracking, and no data collected by us — it's just yours. WHAT THIS APP IS NOT Teacher Time Keeper is a schedule and countdown tool only — it does not manage students, rosters, grades, or attendance. If you need a class/period timer and bell schedule that just works, this is built for exactly that. FEATURES • Six rotation types: same every day, alternating, 3/4/5-day cycles, custom rotating, or by day of week • Live countdown with color-coded blocks • Notifications before class ends so you're always ready to transition — six trigger types (before/after start, before/after end, on start/end) • Home Screen / desktop widget with real-time updates • Apple Watch app with swipe-to-view full day schedule • Watch complications for every face style • Bell-time adjustment for physical bell drift • Full scrolling school calendar with tap-to-override • Bulk no-school day entry for breaks and holidays • 12-hour or 24-hour time display, your choice • Import/export to share your setup with other teachers • iCloud sync across Mac, iPad, iPhone, and Apple Watch — no account required
