# AlarmKit Schedule prominent alarms and countdown timers that surface on the Lock Screen, Dynamic Island, StandBy, and a paired Apple Watch when the alarm fires. AlarmKit requires iOS 26+ / iPadOS 26+. Alarms can break through Focus and Silent mode. AlarmKit uses ActivityKit data models for its Live Activity, but the firing alert is system-managed alarm UI, not a general custom notification UI surface. Custom UI belongs only to countdown and paused Live Activity states rendered by a Widget Extension with the same `AlarmAttributes<Metadata>` and `AlarmPresentationState` used when scheduling. See [references/alarmkit-patterns.md](references/alarmkit-patterns.md) for complete code patterns including authorization, scheduling, countdown timers, snooze handling, and widget setup. ```swift import AlarmKit ``` ## Contents - [Workflow](#workflow) - [Authorization](#authorization) - [Alarm vs Timer Decision](#alarm-vs-timer-decision) - [Scheduling Alarms](#scheduling-alarms) - [Countdown Timers](#countdown-timers) - [Alarm States](#alarm-states) - [AlarmAttributes and AlarmPresentation](#alarmattributes-and-alarmpresentation) - [AlarmButton](#alarmbutton) - [Live Activity Integration](#live-activity-integration) - [Common Mistakes](#common-mistakes) - [Review Checklist](#review-checklist) - [References](#references) ## Workflow ### 1.
