## What is Must?

Turn a calendar event, appointment, or meeting into a system alarm that rings through Silent and Focus. Pick an upcoming event from Apple Calendar or create an alarm by hand, choose when it should ring, and manage it from one focused place.

CALENDAR EVENTS TO SYSTEM ALARMS
• Browse timed events from the next 30 days with read-only calendar access
• Select an event, review its time, and create a separate alarm
• Get an optional notification 5 or 10 minutes before the event
• The must-ring AlarmKit alarm still sounds at the event time
• Calendar details are copied when you create the alarm; later calendar edits do not update it automatically

ALARMS YOU CONTROL
• Create one-time alarms for any future date and time
• Receive a full-screen system alert with sound
• Stop the alarm or use the included 5-minute snooze
• Search, filter, and review active and past alarms
• See when a scheduled alarm needs attention

FREE TO START
• Keep up to two active alarms
• Create manual or calendar-based one-time alarms
• Add an optional 5-minute or 10-minute early heads-up
• View local alarm activity insights

MUST-RING PRO — ONE-TIME PURCHASE
• Keep unlimited active alarms
• Create repeating alarms: daily, weekdays, or weekly on the weekday you select
• Choose flexible custom early heads-up timing
• Use 10, 15, 30-minute, or custom snooze
• Explore private calendar insights for your recent schedule

PRIVATE BY DESIGN
Alarm titles, notes, calendar names, event details, and scheduled times stay on your device. Read-only calendar access is used to create alarms and calculate insights locally. Anonymous product analytics may be used to improve the app, but it does not include your calendar or alarm content. No account is required.

Must-Ring uses Apple’s AlarmKit on iOS 26. Alarm behavior depends on Alarm permission, successful scheduling, and device settings. Must-Ring is not intended for medical, emergency, or safety-critical alerting.
