How the timer works

The countdown is based on your device's clock, so it stays accurate even if you switch to another tab or your browser slows down background pages. When it reaches zero a three-note chime plays and the display flashes. Sound only works after you have pressed Start, because browsers block audio that a page plays on its own.

While the timer runs, supported browsers keep your screen from going to sleep. Keep this tab open: closing it stops the timer.
