Pomodoro Timer

What this tool does

This is a Pomodoro timer: a focus tool that splits your work into timed intervals with built-in breaks. A focus interval runs for 25 minutes by default, followed by a 5-minute short break. After four focus intervals you get a longer 15-minute break, then the cycle repeats. The timer advances through these phases for you — when a focus block ends it moves straight to a break, and when the break ends it sets up the next focus block. A large display shows the time remaining and which phase you are in, a progress bar fills as the interval runs, and a counter tracks how many pomodoros you have completed.

Every length is adjustable. Pause the timer and you can change the focus duration, both break durations, and how many focus intervals pass before a long break. When an interval finishes, a short chime plays so you do not have to watch the screen — and a sound toggle silences it whenever you need quiet.

Use cases

The Pomodoro Technique suits almost any task that needs sustained attention. Writers use it to draft without stopping to edit. Developers use it to stay on one problem instead of drifting between tabs. Students use it to revise in manageable blocks and to build a realistic picture of how long a subject actually takes. It is equally useful for chores and admin: a single 25-minute push is often enough to clear a backlog that felt too big to start.

The breaks matter as much as the focus. Stepping away briefly keeps your mind fresh and makes it easier to begin the next interval. Over a day, the completed counter gives you an honest record of focused time — far more telling than hours spent at a desk.

How to use it

1. Set your durations if the defaults do not suit you — focus length, short break, long break, and how many focus intervals trigger a long break. You must pause the timer to edit these.
2. Press Start, or tap the Space bar, to begin the focus interval.
3. Work until the chime sounds. The timer moves to a break automatically.
4. Use Skip to jump to the next phase early, or Reset to restart the current interval from the top.
5. Reset session clears the completed counter and returns you to a fresh focus interval. The sound toggle mutes or unmutes the end-of-interval chime.

Tips

Protect the focus interval. If a distraction appears, jot it down and deal with it on the break rather than breaking the block — that single habit is what makes the technique work. Treat the break as a real break: stand up, look away from the screen, stretch. Avoid starting something absorbing that you cannot stop when the next interval begins.

If 25 minutes feels too short for deep work, try a 50-minute focus block with a 10-minute break — the ratio is what counts, not the exact numbers. Aim for a sustainable number of pomodoros rather than a record-breaking one; four to eight solid intervals in a day is a strong, repeatable result. Keep the tab open in the background while you work in another app: the timer reads the real clock, so the chime still arrives on time and the remaining time is accurate the moment you switch back.
