Pomodoro Technique Toolv1.0.0
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
Run the Pomodoro Technique end to end without leaving the page. The method, 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 every fourth work session. The structure protects deep attention, prevents fatigue, and creates a measurable cadence you can use to plan and review your day.
- Add tasks in the Add a Task panel by typing a task name, choosing an estimated number of pomodoros, and clicking Add Task. Each task appears in the Your Tasks list and persists across page reloads.
- Click Set Active on the task you want to work on. The active task is highlighted and any pomodoro you complete is automatically logged to its progress count.
- Press Start to begin a 25 minute work session. The timer stage turns red, the page title updates with the countdown, and the session meta line shows your current cycle progress.
- Use Pause if you must step away, then Start to resume from the same second. Use Reset Timer to restart the current session from the beginning, or Skip to jump directly to the next phase without finishing.
- When a work session ends, the timer switches to a short break (teal) or a long break (blue, every fourth completed work session by default). Breaks count down on the same display.
- Open Settings to adjust work duration, short break, long break, and the long break interval. Enable Auto-start next session to chain pomodoros without clicking Start each time, toggle the end of session sound, and opt into browser notifications.
- The formulas are simple: total focused time per task equals completed pomodoros times work duration, and long breaks trigger when the completed pomodoro count modulo the long break interval equals zero.
- Click Mark Done on a task to strike it through and stop logging pomodoros to it. Click the small Delete control to remove a task entirely.
- Use Reset All to clear all tasks, settings, and stored progress. The page returns to defaults and removes its localStorage entry.
Apply the Pomodoro method across knowledge work, study, creative practice, and personal projects. The dynamic task list adapts the technique to real day-to-day work where priorities shift, multiple items compete for attention, and you want a measurable record of focused effort rather 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 the 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 dots 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 colored mode changes 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 stat 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.
