Time Label Sound Volume

In:

Keep this tab open with your volume up — the alarm rings from this page. Alarms are saved in this browser only.

Choose a time (or tap In: 10 min etc.), add an optional label, and pick a sound.
Press Test sound to check your volume, then Add alarm.
When it rings, press Stop or Snooze (5, 9, 10 or 15 minutes).

You can add several alarms and switch each one on or off. Each alarm rings at its time every day while it is switched on.

Leave this page open in a tab. Closing the tab or browser stops the alarm.
Keep your computer awake and plugged in — a sleeping device can't play sound.
On phones, the browser may pause background tabs; for a wake-up alarm on a phone, the built-in clock app is more reliable.

Will the alarm ring if my computer goes to sleep?

No. A web page can't wake a sleeping device. Change your power settings so the screen can turn off but the computer stays awake.

Will the alarm work in a background tab?

Yes, as long as the tab stays open. Browsers slow down background tabs, so the alarm may start a few seconds late, but it still rings.

Are my alarms saved?

Yes, in your browser's local storage on this device. They are not uploaded anywhere.
