Frequently Asked Questions

How do I set a countdown?

Type the hours, minutes and seconds you want, then press Start. The display counts down to zero and shows an alert.

Can I pause and resume the countdown?

Yes. Pause freezes the remaining time; pressing Start again resumes from where you left off.

Will I hear an alert when time is up?

Yes — the timer plays an audible alert and shows a visual notification when the countdown reaches zero. Keep the tab audible for the sound.

Does it work when the tab is in the background?

The countdown keeps running, though some browsers throttle background tabs. For important timing, keep the tab in the foreground.
