The page schedules from timestamps and reconciles after returning to the tab. A closed browser, sleeping device, or suspended tab may prevent an alert.
FAQs
Which time does an alarm use?
It uses the local clock and time presentation supplied by your browser and device.
Will an alarm work in a closed browser or sleeping device?
No guarantee is possible. Closed browsers, sleeping devices, and restricted background tabs can prevent or delay the alert.
Will my alarms still be here when I return?
Yes, in the same browser. Clearing this site's browser data removes them.
How do sound and snooze work?
Test the selected sound after a user action. When an alarm appears, stop it or snooze it for 5 or 10 minutes.
What does Reset remove?
Reset restores the alarm form defaults and exits editing. It does not delete existing alarms.
