Frequently Asked Questions
What is the Pomodoro Technique?
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. You work in focused 25-minute intervals (called "pomodoros") separated by short 5-minute breaks. After every four pomodoros, you take a longer break of 15–30 minutes. The method helps maintain focus and prevents mental fatigue.
Can I change the timer durations?
Yes. Click "Customize timers" below the stats section to open the settings panel. You can adjust the focus duration (1–60 minutes), short break (1–30 minutes), and long break (5–60 minutes) using the sliders. Click "Apply Settings" to save and reset the current timer.
Does the timer continue if I switch tabs?
Yes, the countdown runs as a JavaScript interval and continues running when you switch tabs. The browser tab title also updates with the remaining time so you can see it at a glance. If you grant notification permission, you'll also receive a browser notification when a session ends.
How do I get browser notifications when a session ends?
Click the "Start" button and your browser will ask for notification permission. Once granted, you'll receive a notification whenever a focus session or break ends — even if the tab is in the background.
Is my session data saved?
Today's session stats (focus sessions completed, focus minutes, breaks taken) are stored in memory only for the current page visit. They reset if you refresh the page. No data is stored on a server or in your browser's local storage.
