CalAlarms: カレンダー通知

Calendar notifications are easy to miss. CalAlarms fixes that by turning your upcoming events into real device alarms that cut through silent mode and Do Not Disturb — just like your morning alarm.

HOW IT WORKS

CalAlarms reads your iPhone calendar and automatically schedules alarms before each event. No manual setup. No forgetting. Your phone wakes you up for what matters.

1. Pick which calendars to monitor

2. Set how far in advance you want to be alerted

3. CalAlarms handles the rest

REAL ALARMS, NOT NOTIFICATIONS

This is the key difference. CalAlarms uses Apple's AlarmKit to schedule actual device alarms — the same kind that wakes you up in the morning. They ring even when your phone is on silent. No more missed meetings because a notification got buried.

BUILT FOR VIDEO CALLS

Filter your alarms to only fire before events with video call links. CalAlarms detects Zoom, Google Meet, Microsoft Teams, and WebEx links in your events automatically. Get an alarm before every call, skip everything else.

LIVE ON YOUR LOCK SCREEN

When an alarm fires, a Live Activity appears right on your Lock Screen with event details. See what's coming up and dismiss when you're ready — no need to unlock your phone.

STAYS IN SYNC

CalAlarms syncs automatically in the background:

- When you open the app

- When your calendar changes

- When you move between locations

Your alarms always match your latest calendar.
