Frequently asked questions
Does the countdown make a sound?
Yes. When the countdown reaches zero it plays a short beep using the browser's audio, so you'll notice even if the tab isn't in focus.
Can I pause and resume?
Yes. Both the stopwatch and the countdown pause and continue exactly where you left off without losing your elapsed or remaining time.
Will it keep running if I switch tabs?
The timer keeps tracking real elapsed time based on the clock, so it stays accurate when you return, though the beep may be delayed by the browser if the tab is in the background.
Do I need an account?
No. The timer is completely free and works instantly with no sign-up.
