Frequently asked questions

Does the timer keep running if I switch tabs?
Yes. It tracks the real elapsed time rather than counting ticks, so it stays accurate even if the browser throttles the background tab.
Will it make a sound when it finishes?
Yes, it plays an alarm tone at zero. Make sure your device isn't muted; the first interaction with the page enables audio.
