Pomodoro Timer
Work in 25-minute focus blocks with 5-minute breaks, plus a long break every 4 pomodoros. All durations are adjustable, and a chime plays at every phase change. Just keep the tab open.
How the Pomodoro Technique works
Created by Francesco Cirillo in the late 1980s (and named after his tomato-shaped kitchen timer: "pomodoro" is Italian for tomato), the technique splits your work into 25-minute blocks of total concentration, each followed by a 5-minute break. After every 4 completed pomodoros you take a longer break of 15–30 minutes. During a focus block there is exactly one rule: no interruptions. If a distraction pops up, jot it down and deal with it on your next break instead of switching tasks.
Why 25 minutes actually works
A short block with a visible finish line lowers the resistance to getting started: it's far easier to commit to "just 25 minutes" than to a whole afternoon. Regular breaks prevent the attention dip that sets in after 40–50 minutes of continuous work, and the pomodoro counter turns your day into measurable units, 8 to 12 pomodoros add up to a solid day of deep work. This timer moves between focus and break phases on its own and chimes at every switch, so you never have to watch the clock.
The other timers on the site keep time the same way, with the clock rather than by counting ticks, so they stay exact in a background tab too: Timer, Interval timer (HIIT), Guided breathing, Stopwatch and Event countdown.
