Frequently Asked Questions

What is the Pomodoro Technique?
The Pomodoro Technique is a time management method: focus on work for 25 minutes, then take a 5-minute break. After 4 cycles, take a longer break. This helps maintain focus and prevent burnout.
Does the timer keep running if I close the browser?
The timer requires the browser tab to remain open. Closing the browser or tab will stop the timer. Use fullscreen mode to avoid accidentally closing the tab.
How many timers can I run simultaneously?
The main timer plus any additional timers you create — there is no limit. Each timer runs independently and can be started, paused, and reset separately.
How long does the audio alert last?
A short notification beep plays when the timer completes. The sound is generated using Web Audio API — no external audio files are needed.
Can I customize Pomodoro durations?
Yes. Work time can be set from 1 to 120 minutes, and break time from 1 to 60 minutes. Adjust them to fit your personal workflow.
