Frequently Asked Questions

Does the countdown timer work offline?
Yes. The timer runs entirely in your browser and does not require an internet connection once the page is loaded.
Will I hear a sound when the timer ends?
By default, yes — three short beeps play when the countdown reaches zero. You can turn this off with the sound toggle before or during the countdown.
Can I pause and resume the timer?
Yes. Use Pause to stop the countdown and Resume to continue from where you left off. Reset clears the timer so you can set a new duration.
