Calendar alarms for real-world scheduling problems

Standard calendar notifications are easy to dismiss. Beacon Calendar uses calendar-triggered alarms so critical events are much harder to miss.

Meetings missed on Silent or Do Not Disturb

If your phone stays on Silent or Do Not Disturb during deep work, Beacon Calendar can turn event notifications into alarms so meeting reminders are harder to ignore.

Shift workers and rotating schedules

When shifts change every week, fixed alarms fail. Beacon Calendar follows your actual calendar so alarm times update automatically as shifts move.

Irregular hours and must-make events

For flights, interviews, and deadlines, calendar-powered alarms reduce the chance you miss high-stakes events because a notification was swiped away.

How Beacon works

Calendar-powered

Beacon reads your calendar events and schedules alarms automatically — no manual entry required.

Smart alarm rules

Create rules that match events by name, attendees, keywords, and more. Set your alarm offset once - Beacon does the rest.

Always on time

Powered by Apple's AlarmKit, alarms fire reliably even when the app is closed or in the background.

FAQ

Last updated: July 16, 2026

How do I make sure I don't miss meetings when my phone is on silent?

Use calendar-triggered alarms instead of standard calendar notifications. Beacon Calendar schedules iOS alarms from your events so they are harder to miss when your phone is on Silent.

Can I get an alarm (not just a notification) for calendar events?

Yes. Beacon Calendar creates true iOS alarms for matching events, not just lightweight notifications that are easy to swipe away.

What's a good alarm app for shift workers and rotating schedules?

An app that reads your live calendar and auto-schedules alarms is usually best for rotating schedules. Beacon Calendar uses rules so your alarms adapt as shifts change.

Do calendar alarms work with Google Calendar, Outlook, and iCloud?

Yes, if those calendars are synced to your iPhone calendar accounts. Beacon Calendar reads events available on your device and can trigger alarms from them.

Will the alarm ring on Do Not Disturb?

Yes, Beacon Calendar is designed around iOS alarm behavior that can ring through Do Not Disturb and Silent Mode. Keep alarm volume and permissions configured so alarms can fire correctly.

Is my calendar data private?

Yes. Beacon Calendar is designed to keep your event and alarm data on your device, and your privacy page explains that your calendar data is not uploaded to external servers.
