Pomodoro Timer
A focus timer that cycles through 25-minute work sessions and short and long breaks, using the classic Pomodoro Technique — right inside your browser.
What is the Pomodoro Technique?
The Pomodoro Technique breaks work into focused 25-minute sessions separated by short breaks, with a longer break after every four sessions. The structure helps keep concentration high and prevents burnout by building in regular rest, rather than working in one long unbroken stretch.
GuideHow to use it
How the timer works
Each focus session runs for 25 minutes, followed by a 5-minute short break. After every fourth completed focus session, the next break extends to 15 minutes before the cycle continues. You can switch phases manually at any time using the tabs above the timer.
Why it helpsFeatures & benefits
Why this runs entirely in your browser
The timer runs in JavaScript locally in the tab, which means it keeps working offline once the page has loaded and nothing about your sessions is ever sent to a server.
Common uses
Staying focused during deep work or study sessions, structuring a work block with built-in breaks, or timing a series of short tasks with regular rest periods.
