Pomodoro Timer

📖 Tool Introduction

The Pomodoro Timer is an online focus stopwatch built on the classic Pomodoro Technique. Invented by Francesco Cirillo in the 1980s, the method breaks work into 25-minute focused sprints, each followed by a 5-minute break, and every four sprints earns you a longer 15-to-30-minute rest. Countless office workers and students have proved that this rhythm beats procrastination, fights scattered attention and lifts the quality of every hour you put in. This timer runs entirely inside your browser, so there is nothing to install and no account to sign up for. The ring around the digits shrinks smoothly as the countdown progresses, giving you an intuitive sense of how much time remains. When a session ends, a short clear tone tells you to switch gears, so you never drift into overtime or forget to rest. Focus, short break and long break durations are all adjustable, as is the number of focus rounds between long breaks, which means you can tune the whole cycle to match your own attention rhythm. Completed pomodoros and total focused minutes are counted live below the dial, so you can quantify exactly how deep into work you have gone each day. The layout is deliberately clean, supports three languages, and stays comfortable even in dark mode, which makes it a natural companion for exam study, deep coding, long writing sessions and any other task that demands uninterrupted concentration. The whole experience is designed to be frictionless: no accounts, no ads, no cloud sync, no distracting notifications, just you and a single calming ring that guides your attention from one focused block to the next.

⚠️ Notes

• Timing accuracy: the timer is driven by setInterval; background tabs may be throttled, so keep this page visible
• Audio permission: browsers only allow sound after a user gesture, so click once first to unlock the chime
• Valid ranges: focus 1-90 min, short break 1-30 min, long break 5-60 min; out-of-range values trigger a notice
• Fully local: every countdown and statistic runs in your browser with zero network requests
• Reset on refresh: settings return to defaults on page reload, so re-apply your custom values after refresh
