Frequently asked questions
Does it keep running after I close the page?
Timing depends on the current page, so closing or refreshing stops it — keep the tab open to continue timing.
What happens when the countdown ends?
A clear on-page alert appears at zero; keep your device volume on if you also want to hear it.
Do I need an app?
No, it works in the browser; on mobile you can add the page to your home screen to use it like an app.
