Frequently Asked Questions
Will the timer keep running if I switch tabs?
Yes, but some browsers throttle background timers. For critical timing, keep the tab visible or use a dedicated app.
Is there an alarm when the timer finishes?
A 'Time's up!' indicator appears when the countdown reaches zero. Browser audio alerts require user permission and are not included.
What is the Pomodoro technique?
A time management method using 25-minute focused work sessions followed by 5-minute breaks. The preset sets 25:00 for easy Pomodoro use.
