## What is Calendar Alarm?

Never miss an important event because of a silent notification.

Unmissable turns your calendar events into real system alarms - the kind that ring clearly when ordinary notifications are easy to miss. It is built for meetings, appointments, calls, classes, and anything you do not want to forget.

REAL ALARMS FOR CALENDAR EVENTS
Choose any upcoming event and set a real alarm with one tap. The alarm can ring at the event time or a few minutes before, with snooze and an optional pre-alarm countdown.

YOUR ALARM STAYS VISIBLE
- Live Activity countdown on the Lock Screen when available
- Dynamic Island shows alarm status
- Lock Screen and Home Screen widgets give you a quick glance

SIMPLE CONTROL
See upcoming events and alarm status in one place. Search, sort, and filter events, then customize alarm settings per event when needed.

SMART DEFAULTS
Set alarm timing and snooze once for new alarms, then override individual events when they need special handling.

PRIVATE BY DEFAULT
No accounts. No tracking. No analytics. No ads. No cloud sync. Your calendar and alarm data stay on your device.

ONE-TIME PURCHASE
The free version includes 1 active alarm. One purchase gives you lifetime access to unlimited alarms, widgets, alarm history, weekly stats, and Family Sharing. No subscription.

Works with iCloud Calendar, Google Calendar, Outlook, and any calendar added to your device.

### 3/5 — Support email bounced back undeliverable, nonexistent domaiin msg received

*2026-07-31*

I really like the app and was considering purchasing Pro. However, both the in-app ‘Contact Support’ option and the App Store ‘App Support’ link generate an email to a non-existent domain. The email bounces immediately with ‘domain couldn’t be found.’ I hope this is fixed because the app itself is promising.

**Developer response:** Thank you for flagging this — you were right, and it is fixed. Our support address had changed and the old one bounced. Both the in-app Contact Support and the App Store support link now reach us at developer@crafterapps.com. We are sorry your first message got lost; if you still have questions about Pro, email us any time and we will answer personally. — Crafter Apps
