Frequently Asked Questions
What is the Pomodoro Technique? expand_more
A time-management method developed by Francesco Cirillo in the 1980s. You work in 25-minute focused "pomodoros" separated by short breaks, with a longer break after every fourth pomodoro.
Can I customize the durations? expand_more
Yes. Expand the Customize panel to set focus, short, and long break lengths in minutes. Changes apply immediately to the next phase.
Does the timer keep running if I close the tab? expand_more
No. The timer pauses if you navigate away or close the tab. Keep this tab open or use a dedicated app for background timing.
Need to count down to a calendar event instead? expand_more
Use the [Countdown Timer](/tools/countdown-timer/) for an absolute target date.
