Locally saved alarms
Online alarm clock
Keep this page open for alarms. Alerts may not sound when your device is locked or asleep.
Alarm
Create multiple labeled alarms, choose repeat days and sounds, and keep them saved in this browser.
Important browser limitation
A normal web page cannot guarantee an alarm after the browser, tab, device, or operating system suspends or closes it. Keep this page active for the most reliable result; use your device alarm for critical reminders.
Private local storage
Alarm settings are stored locally in this browser. There is no account or server database, so alarms do not sync between devices.
