Install

npm install @capgo/capacitor-alarm
npx cap sync

Requirements

• iOS: iOS 26+ only. This plugin relies on AlarmKit APIs and will report unsupported on earlier versions or when the framework is unavailable.
• Android: Uses AlarmClock intents; behavior depends on the default Clock app and OEM policies.

Note: This plugin only exposes native alarm actions (create/open). It does not implement any custom in-app alarm scheduling/CRUD.
