Alarm time

Label (optional)

Alarm at 22:54

This alarm works while the tab stays open and visible — browsers pause audio and timers in background tabs. It needs one click (like pressing Set alarm) before it may play sound. For alarms that must survive closing the browser, use your device's clock app.
