Frequently asked questions
Does it still work if I switch tabs?
Yes — the countdown is based on the actual clock time it should finish at, not on the tab staying active, so switching away and back still shows the correct remaining time.
Will it make a sound when it finishes?
Yes, a short alert tone plays automatically when the timer reaches zero, generated in your browser — no audio file to load.
