Frequently asked questions
Does the timer keep running if I switch tabs?
Yes — it uses the system clock so it stays accurate even after the tab is throttled.
Will the alarm sound on mobile?
Yes, as long as your device is not muted and the page is open in a foreground tab.
Can I set multiple timers?
Open the tool in several browser tabs and label each one — every tab tracks its own countdown.
Is there a Pomodoro preset?
You can manually set 25:00 to follow the standard Pomodoro work interval.
Does it work offline?
Yes, once the page is loaded the countdown runs entirely client-side.
