Stay focused with timed work sessions and breaks

How it works
The Pomodoro Technique is a time-management method developed by Francesco Cirillo in the late 1980s. Cirillo used a tomato-shaped kitchen timer (pomodoro is Italian for tomato) to structure his university study sessions into short, focused blocks. The method spread through productivity circles and remains one of the most widely used approaches for sustained concentration.
The core idea is alternating focused work with regular breaks. Working in bounded intervals helps you commit fully to a single task, while scheduled rest prevents the mental fatigue that builds during long, uninterrupted stretches. Research on attention and cognitive load suggests that brief breaks can support sustained performance — though results vary by person and task. The technique works best as a structure you adapt, not a rigid rule.
Clockr's Pomodoro timer follows the classic 25-minute work session, 5-minute short break, and 15-minute long break after every four sessions. Open "Customise timings" below the controls to adjust work length, break duration, or how many sessions run before a long break — useful if you prefer longer deep-work blocks or shorter sprints.
Frequently asked questions
What is the Pomodoro Technique?
The Pomodoro Technique is a focus method where you work in timed intervals (traditionally 25 minutes) separated by short breaks. After completing four work sessions, you take a longer break before starting the next cycle. The goal is to make deep work feel manageable and to build a rhythm of concentration and recovery throughout the day.
How long should a Pomodoro work session be?
The standard length is 25 minutes, which Cirillo found effective for study sessions. Many people use 25 to 50 minutes depending on the task — shorter blocks suit admin and email; longer blocks suit writing, coding, or design. Start with 25 minutes and adjust using the settings panel if you find yourself stopping early or needing more time to reach flow.
Why is it called the Pomodoro Technique?
Francesco Cirillo named the method after the tomato-shaped kitchen timer he used as a student in the late 1980s. Pomodoro means tomato in Italian. The playful name stuck even as the technique moved from physical timers to apps and browser tools like this one.
Can I customise the work and break durations?
Yes. Click "Customise timings" on the timer to change work length, short break, long break, and the number of sessions before a long break. Pause or reset the timer first if it is running — settings apply to the next session once you adjust them. Defaults match the classic 25 / 5 / 15 minute pattern with four sessions per cycle.
How many Pomodoro sessions should I do per day?
There is no fixed target — it depends on your schedule and energy. Eight focused pomodoros (about four hours of deep work) is a common daily goal for knowledge workers, but two to four sessions can be meaningful on busy days. Quality matters more than quantity: fully disengage during breaks, and stop when concentration drops rather than forcing extra rounds.
Does this timer work if I switch tabs or browsers?
The timer runs in your browser using JavaScript, so it continues while the Clockr tab is open. Background tabs may be throttled by your browser, which can slightly delay updates and the end-of-phase chime. For the most reliable experience, keep this tab visible or pinned while a session is active. Closing the tab or browser stops the timer.
