Pomodoro Timer

How the Pomodoro rhythm works

The Pomodoro technique breaks work into fixed intervals: a 25-minute focused session followed by a 5-minute break, with a longer break after four sessions. The timer enforces the rhythm so you work in bounded sprints rather than open-ended slogs, which makes it easier to start a daunting task and easier to stop before burning out.

When you reach for it

Useful for deep work that keeps getting interrupted, for tasks you keep putting off because they feel large, or for pacing a long day so you take breaks you would otherwise skip. The fixed interval is also a natural unit for estimating: "this will take about three pomodoros" is a surprisingly honest measure.

Example

Session 1  25:00  focus
Break      05:00
Session 2  25:00  focus
Break      05:00
Session 3  25:00  focus
Break      05:00
Session 4  25:00  focus
Long break 15:00

Common pitfalls

The intervals are a default, not a law. For tasks that need a long runway to get into flow, a rigid 25-minute cutoff can interrupt you right as you hit your stride, so lengthening the focus block is reasonable. The break matters as much as the work: skipping it to "keep going" defeats the purpose, since the technique's benefit comes from the recovery. A browser-based timer also pauses or throttles in a backgrounded tab on some systems, so a timer running in an inactive tab may drift or stall; keep it visible or rely on a notification. For related focus tooling, the typing speed test makes a decent warm-up.

FAQ

Why does the timer drift when the tab is hidden? Browsers throttle timers in background tabs to save power. Keep the tab active or use a notification-based timer.

Can I change the 25-minute length? Yes. The ratio matters more than the exact number; adjust it to your attention span and task.

Do breaks really help? Yes, that is the core idea. The scheduled rest is what keeps focus sustainable across a full day.
