Pomodoro Technique Tool
Configurable Pomodoro timer with adjustable work, short break, and long break durations (defaults 25/5/15 minutes) and a selectable long-break cadence. Long break triggers every 2 to 12 completed work sessions (default 4). Tasks tracked alongside the timer carry per-task estimated and completed pomodoro counts; cumulative focus minutes equal completed work sessions times the current work duration.

Documentation
The Pomodoro Technique, created by Francesco Cirillo in the late 1980s, divides work into focused intervals, traditionally 25 minutes, separated by short recovery breaks, with a longer break after a set number of work sessions. The structure protects deep attention, prevents fatigue, and creates a measurable cadence for planning and reviewing a day of work.
Each task carries a name and an estimated pomodoro count; only one task is active at a time, and every completed work session logs automatically to whichever task is active, building an actual-versus-estimated record per task. Pausing preserves the elapsed time so a session resumes from the same second rather than restarting, and skipping jumps straight to the next phase without crediting the current one as complete. When a work session ends, the timer switches to a short break, or to a long break on the session count set as the long break interval (adjustable from 2 to 12 sessions, default 4). Work duration, short break length, long break length, and the long break interval are all adjustable in Settings, along with auto-starting the next session automatically, an end-of-session sound, and browser notifications.
Total focused time for a task equals its completed pomodoro count multiplied by the current work duration, and a long break triggers whenever the completed pomodoro count is an exact multiple of the long break interval; every other completed session triggers a short break instead. Marking a task done stops further pomodoros from logging against it without deleting its history.
At the default 25 minute work duration, four completed pomodoros equal 100 minutes of tracked focus time (4 x 25). With the default long break interval of 4, the fourth, eighth, and twelfth completed pomodoro each trigger a long break, while the first, second, third, fifth, sixth, and seventh trigger a short break.
Apply the Pomodoro method across knowledge work, study, creative practice, and personal projects. A dynamic task list adapts the technique to real day-to-day work where priorities shift, multiple items compete for attention, and a measurable record of focused effort matters more than vague time blocks.
- Software Development: A backend engineer assigns three pomodoros to a tricky database migration, two to code review, and one to writing the rollout plan. Tracking actual versus estimated pomodoros surfaces which tasks are consistently underestimated and improves future sprint planning.
- Writing and Content: A freelance writer sets a 50 minute work interval and a 10 minute break to match a longer attention span. Four pomodoros on a draft, one on edits, and one on outreach gives a clean record of billable focus time per client.
- Studying for Exams: A medical student stacks pomodoros against flashcard decks, practice questions, and reading. Short breaks after each session reduce mental fatigue, and a long break interval of four enforces a real pause every two hours of study.
- Research and Analysis: A data analyst breaks an investigation into discrete questions, assigns one to two pomodoros per question, and uses the cycle count to know when to step away from the screen before pattern matching degrades.
- ADHD and Focus Support: A user prone to context switching shortens work intervals to 15 minutes with three minute breaks. The visible countdown and the change in phase at each transition provide external structure that makes sustained focus more attainable.
- Creative Practice: A musician dedicates pomodoros to technique drills, repertoire, and sight reading, and uses the completed pomodoros count as a weekly practice log.
- Administrative Work: A project manager batches email triage, invoice review, and status updates into a single pomodoro each, then switches to a longer block for the week's strategic planning task.
