The technique in one paragraph
The Pomodoro Technique, developed by Francesco Cirillo in the late 1980s, breaks work into fixed intervals separated by short breaks. The classic pattern is twenty-five minutes of single-task focus followed by a five-minute break, with a longer break of fifteen to thirty minutes after every fourth interval. The point is not the specific numbers — it is that a bounded interval makes starting easier, and a scheduled break stops the interval from stretching until your attention is gone.
Why the intervals are adjustable here
Twenty-five minutes is a starting point, not a rule, and most timers treat it as one. Deep technical work often needs a longer runway before it becomes productive, so fifty or ninety minutes with a proper break may suit it better. Work that is genuinely hard to start sometimes needs a much shorter interval — ten minutes is enough to get past the resistance. Set focus length, short break, long break and the cycle count independently, and the timer keeps your pattern.
Reading the cycle counter
The counter shows how many focus intervals you have completed and how many remain before the long break. When the counter reaches your chosen interval, the next break is the long one and the count starts again. It carries on until you stop it, so you can leave it running across an afternoon.
