Frequently Asked Questions
How does the Pomodoro Timer work?
The timer stores a timeLeft counter in seconds and decrements it each second via setInterval. A state machine tracks the current mode (work, shortBreak, longBreak) and a session counter. When timeLeft reaches zero, the mode auto-advances: work sessions rotate to short breaks, and every fourth completed work session triggers a long break. The SVG progress ring uses strokeDashoffset calculated from elapsed-to-total ratio.
What is the Pomodoro technique?
It is a time management method where you work in focused 25-minute intervals (called pomodoros) separated by 5-minute breaks. After four pomodoros, you take a longer 15-30 minute break.
Can I customize the work and break durations?
Yes. You can adjust the work interval, short break, and long break durations to match your personal focus style. Some people prefer 50/10 or 45/15 splits.
Will I get notified when a session ends?
Yes. The timer sends a browser notification and plays a sound when each work or break period finishes, so you can step away from the screen during breaks.
