ScheduleLock is the alarm app built for teachers on rotating block schedules. Set your alarms once, and the app fires the right ones for whatever today is — A-Day, B-Day, Day 4 of a 6-day rotation, or any pattern your school uses. When the day changes, one tap handles it. WHO IT'S FOR Teachers, coaches, and staff at schools that run rotating block schedules. If your day is "A-Day, B-Day, A-Day…" or "Day 1 through Day 6," ScheduleLock is built for you. HOW IT WORKS • Tell ScheduleLock your term start, term end, and rotation pattern once during setup. • Build alarm groups for each day type (e.g. "A-Day Alarms," "Day 3 Alarms," "Every School Day"). • Each morning the app fires only the alarms that belong to today. • Weekends and dates outside your term are skipped automatically. ONE-TAP DAY OVERRIDE Snow day, two-hour delay, assembly schedule, dentist appointment? Tap Day Override: • Full Day Off — silences every alarm for today. • Custom — silence specific alarms only, keep the rest. Tomorrow returns to your normal rotation automatically. No re-arming, no remembering. RELIABLE BY DESIGN • Local alarms scheduled with the device's exact-alarm system — no push servers, no cloud, no delay. • Works fully offline. No internet, no account, no sign-in, ever. • Survives device reboots — pending alarms are restored after restart. • Custom labels per alarm, snooze duration of your choice, choice of built-in alarm sounds. PRIVACY YOU CAN VERIFY • No ads. • No tracking, no analytics, no telemetry. • No network access — your schedule stays on your device. • No account required. Free to install. Built for teachers, not advertisers. ## Key features - Rotating schedule alarm automation - One-tap day overrides - Customizable alarm groups - Offline functionality - No ads or tracking - Reliable local alarm system ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/schedulelock-teacher-alarms/id6763806869/reviews.md ### 5/5 — Perfect solution for school alarms *2026-08-27* I wish this had the ability to choose custom songs or had more sounds to work with from iOS clock sounds. But this app is perfect for school alarms that are at different times on A vs B days ### 4/5 — Good, but what about early release schedules? *2026-08-26* I love that I can set multiple alarms through the day (my school doesn’t use bells), but I wish I could add an Early Release schedule only on certain days of the school year. ## Frequently asked questions about ScheduleLock ### How does ScheduleLock handle different school day rotations?
