About Alarm Clock
This alarm clock rings at a time you choose and shows how long is left. Set several alarms with labels, repeat one every day, snooze a ringing alarm for five minutes and test the sound before you rely on it. A clock at the top shows the current time, down to the second, and each alarm lists when it will next ring.
A web page can only ring while it is open. If you close it, if the browser freezes the tab to save power or if the device is asleep or muted, the alarm will not sound, so keep the page visible with the screen on and the volume up, and use a phone alarm as well for anything important. Browsers also hold back sound until you have pressed a button, which is why there is a Test the sound button. If an alarm time is skipped when the clocks go forward in spring, the alarm rings an hour later.

Frequently asked questions
Will the alarm ring if I close the page?
No. It works only while the page is open and the device is awake. Use a phone alarm for anything important.
Why was there no sound?
The volume may be off, the device muted or the browser may have blocked sound. Press Test the sound after opening the page to allow it.
What happens when the clocks change?
An alarm always rings at the clock time. If the time does not exist because the clocks go forward, it rings an hour later; when the clocks go back it rings once.
Can I set more than one alarm?
Yes. Each alarm has its own label and appears in the list with the time left.
How long does it ring?
It repeats the sound for up to two minutes unless you press Stop or Snooze.
