About Ultimate Calendar Alarm
Turn events in your Android calendar into wake-up-style alarms.
Create an alarm by starting a calendar event title with @CAL followed by the number of minutes before the event when it should ring:
• @CAL30 Team meeting — rings 30 minutes before event
• @CAL240 Flight — rings 4 hours before event
• @CAL0 Appointment — rings when the event starts
Ultimate Calendar Alarm can use eligible events from calendars synchronized to your device, including shared calendars. Upcoming alarms are listed in the app so you can see exactly what is scheduled.
Features include:
• Loud, persistent wake-up-style alarms
• Snooze and dismiss controls
• Your choice of available system alarm sounds
• Automatic rebuilding after calendar changes, daily maintenance, phone restarts, and relevant system changes
• Manual Refresh Alarms control
• Setup guidance for notifications, exact alarms, Do Not Disturb, and full-screen alarms
• 30-day free trial
• One-time lifetime purchase after the trial
Calendar and alarm information is processed locally on your device and is not sent to E-Soft.
Ultimate Calendar Alarm is a general-purpose calendar reminder. Do not rely on it for medical, emergency, or other safety-critical purposes.
