Keep this tab open. If you switch tabs the timer keeps time; if the phone sleeps or the browser pauses the tab, it shows the right time the moment you return, but it cannot ring while the tab is asleep.

Questions
Will the timer keep running if I switch tabs?
Yes. It works from the time it will end, not by counting seconds, so it stays right in the background. A phone that sleeps can pause the tab: the timer shows the right time again the moment you return, but it cannot ring while the tab is asleep. To set a timer for any length, such as 4, 11 or 13 minutes, type the minutes into the online countdown timer; the 1, 2, 3, 5, 10, 15, 20, 25 and 30 minute timers start with one tap.
What if I close or reload the page?
A running timer is kept on this device, so reopening the page shows how much time is left, or that it has finished.
