Frequently Asked Questions

Will the timer work if I switch browser tabs?

Yes — the timer continues to run in the background even if you switch to another tab. However, some browsers may slow background JavaScript slightly, so for the most accurate timing, keep the tab visible.

Can I run multiple timers at once?

Yes — click the Add Timer button to create additional countdown timers that run independently and simultaneously.

Does it make a sound when the timer ends?

Yes — the timer plays an alert sound when it reaches zero. Make sure your device volume is turned up so you don't miss the notification.

What is the difference between a timer and a stopwatch?

A timer counts down from a set time to zero. A stopwatch counts up from zero to measure elapsed time. Both are available on this page.

Is there a maximum countdown time?

You can set a countdown of up to 99 hours, 59 minutes, and 59 seconds — more than enough for any practical use case.
