Keep track of class transitions with ClassBell Alarm, your personal school bell schedule companion. CREATE CUSTOM SCHEDULES Build unlimited bell schedules with as many periods as you need. Whether you have a regular 8-period day, block scheduling, or special assembly days — ClassBell handles it all. REAL-TIME COUNTDOWN See exactly how much time remains in your current period with a beautiful countdown display. A visual progress bar shows you at a glance where you are in your day. BELL NOTIFICATIONS Choose Bell, Chime, or Subtle as iPhone notification sounds for ClassBell's time-sensitive notifications, and add up to three warnings to each period. On iPhone, sounds follow Silent mode, Focus, and notification settings. Apple normally alerts your iPhone or Apple Watch, not both: an unlocked iPhone receives the alert; when the phone is locked, an eligible worn, unlocked Watch normally receives it. A paired Apple Watch uses its own sound and Silent settings, so silence the Watch too when quiet is required. iOS and watchOS control haptics; check your device settings and run a test before class. AUTOMATIC DAY DETECTION Assign schedules to weekdays, one-time dates, or an alternating A/B calendar. ClassBell resolves the exact schedule for each school day while still letting you start any schedule manually. SIRI & SHORTCUTS Start today's schedule, begin again from Period 1, hold, resume, or end a schedule with Siri or the Shortcuts app. You can also open Confidence Center directly when you want a quick readiness check. CONFIDENCE CENTER See notification permission and sound status, Live Activity status, and recent scheduling actions in one clear place. ClassBell explains how Silent mode, Focus, and Apple Watch routing can affect delivery without implying that it uses your microphone or records your screen. BEAUTIFUL DESIGN Enjoy a clean, modern interface with full dark mode support. Customize your accent color to match your style. PRIVATE BY DESIGN ClassBell works offline and does not require an account. Optional manual backups are stored in your private iCloud container, never on ClassBell's servers. HOME SCREEN WIDGETS Add small, medium, and large Home Screen widgets for current, next, and upcoming periods. The native period-boundary timelines keep the display aligned with your schedule, and you can tap to open Today. KEY FEATURES • Create unlimited schedules and periods • Live countdown timer with progress bar • Pre-end warning notifications • Three iPhone notification sounds: Bell, Chime, and Subtle • Automatic schedule suggestions by day • Alternating A/B rotation calendars and date-specific schedules • Siri and Shortcuts controls • Confidence Center readiness and recent-action history • Quick setup wizard for fast schedule creation • Dark and light theme support • Small, medium, and large Home Screen widgets • Works offline — no ClassBell account required Perfect for students, teachers, and anyone who follows a timed daily routine.
