Pomodoro Timer

The Pomodoro Technique turns an overwhelming day into a series of small, winnable races: 25 minutes of single-task focus, then a 5-minute break, and after four rounds a longer rest. This timer runs the full cycle for you — focus, short break, long break — counting your completed sessions and sounding a gentle alarm at each switch, so your brain can stop watching the clock and just work the interval it is in. Session lengths are adjustable for those who prefer 50/10 or deep-work 90-minute blocks, but the defaults are the classic recipe, unchanged because it works: short enough to start, long enough to matter.

Quick Answer: Press Start to begin a 25-minute focus session; the timer automatically cycles to a 5-minute break, with a long break after four sessions.

How to Use the Pomodoro Timer

Choose your mode lengths if the classic 25/5/15 does not suit you.
Press Start Focus and work on exactly one task until the alarm.
When the break starts, actually break — stand, stretch, look far away.
Repeat; after four focus sessions the long break arrives automatically.
Watch the completed-sessions counter and stop at your planned number for the day.

Key Features

Full automatic cycle: focus → short breaks → long break every 4.
Adjustable focus, short-break and long-break lengths.
Completed session counter for daily tracking.
Audible alarm plus clear phase display at every switch.
Clock-based timing stays accurate in a background tab.

Best Practices and Tips

Write the one task on paper before starting; the technique fails politely but completely when the session has no defined job.
If an interruption lands mid-session, note it and return — the tomato is about protected attention, not perfection.
Use the break properly: screens and feeds do not restore attention; distance, movement and daylight do.
Two cycles is a respectable day for genuinely hard work; plan the day in sessions, not hours.
If 25 minutes feels trivially short for your work, deepen to 50/10 rather than abandoning the rhythm.

Common Mistakes to Avoid

Pausing the timer ‘just for a minute’ to check messages — the session is the promise; breaking it teaches your brain the timer is negotiable.
Skipping breaks to ‘stay in flow’, then wondering why session four produces nothing.
Running the timer while multitasking three tabs of work — the technique counts focus, and so does the quality of the output.
Setting heroic session counts on day one; build the habit at two to four sessions, then grow.

Frequently Asked Questions

What are the classic Pomodoro lengths?

25 minutes of focus, a 5-minute break, and a 15-30 minute long break after four focus sessions. The defaults here follow the original technique; adjust them in the settings if your work runs on a different rhythm.

Why does the technique work?

It attacks the two enemies of deep work: starting friction (25 minutes is too small to fear) and attention drift (a break is always near, so the mind stops negotiating for one). The session counter adds the quiet motivation of a streak.

Will the alarm sound in a background tab?

The phase timing is computed from the real clock, so switches happen on time. Alarm audio in background tabs depends on the browser, but the phase and counts are correct the moment you return, and most browsers play the sound.

Can I use it for studying and meetings?

Certainly — students use it for revision blocks, and some teams run facilitated work sprints on the same cycle. It is a timer with a philosophy, and the philosophy — single task, defined interval, real break — transfers anywhere.

What happens after the long break?

The cycle resets and session counting continues, so a full day reads as multiples of four. Stop whenever your planned sessions are done — the counter, not exhaustion, should end the day.
