Alarm Clock
time
1. How to Use
- Enter an alarm name (optional, defaults to 'My Alarm') and select time using AM/PM, hour, and minute.
- Click 'Add Alarm' to add the alarm to your list. Alarms are stored in your browser and persist across sessions.
- Enable browser notifications when prompted for reliable alerts even when the tab is in the background.
- Toggle the bell icon to enable or disable an alarm. Click the edit icon to change the time or name.
- Click 'Delete' to remove an alarm. When an alarm triggers, a modal and sound will notify you.
2. How It Works
The alarm clock checks the current time every second against your set alarms. When the hour and minute match and the alarm is active, it triggers.
Multiple notification channels are used: a visual modal popup, Web Audio API beep sound (or fallback audio), and browser Notification API if permitted.
Alarms are stored in localStorage by date. Each alarm has id, name, time (24h format), and active status.
