Frequently Asked Questions

What is the Pomodoro Technique? +

The Pomodoro Technique is a time management method developed by Francesco Cirillo. You work for 25 minutes (one "Pomodoro"), then take a 5-minute break. After 4 Pomodoros, take a longer 15–30 minute break. This improves focus and reduces mental fatigue.

Can I customize the timer duration? +

Yes — click the settings icon to change the work session length, short break length, and long break length. Common customizations are 50/10 (deep work sessions) or 45/15 for academic study.

Will the timer notify me when it ends? +

Yes — the timer plays a sound alert when each session ends. If you allow browser notifications, you will also receive a desktop notification even if the tab is in the background.

Does the timer keep running if I switch tabs? +

Yes. The timer uses JavaScript's setInterval and timestamps so it continues accurately even when the tab is not active. The tab title shows the remaining time so you can see it without switching back.

What happens after 4 Pomodoros? +

After completing 4 work sessions, the timer automatically suggests a long break (15 minutes by default). The session counter tracks your completed Pomodoros so you know how many cycles you have finished.
