CalAlarm — Calendar Alarms

■ Notifications get missed. Alarms don't.

Ever missed a meeting because the calendar banner vanished in a second — or never made a sound in Silent or Focus mode?

CalAlarm turns just the events you can't afford to miss into full-strength alarms, powered by the same mechanism as the Clock app.

■ One switch. That's the whole workflow.

• Your next 7 days of calendar events, listed automatically
• Flip the switch on the important ones — they become alarms
• No more copying times into the Clock app by hand

■ Rings through Silent and Focus

Built on iOS's alarm engine — the same one the Clock app uses. Silent switch on? Do Not Disturb? It rings until you stop it.

■ When your calendar moves, alarms move too

• Meeting moved from 10 to 11? The alarm follows automatically
• Event deleted? The alarm is removed
• Your calendar is the source of truth — always in sync

■ Flexible lead times

• Set a global default (on time – 1 hour before)
• Override per event: dentist 30 min early, stand-up 5 min

■ Quick Alarms

For errands too small for the calendar: a label, Today/Tomorrow, a time. Three seconds.

■ Home Screen widget

See upcoming events and alarm states at a glance, and toggle alarms with a tap — without opening the app.

■ Privacy first

• No account. No server.
• Your calendar content never leaves your device
• No tracking. No ads.

■ Made for you if…

• You've been late because you missed a calendar notification
• You keep re-checking the clock before important events
• You manually re-type event times into the Clock app
• Working from home, you fear joining meetings late
• You prefer simple, pay-once tools

■ Requirements

Requires an iPhone running iOS 26 or later (uses the system's Clock-grade alarm engine).
