A full explanation of the pomodoro method, the 25/5 rule, and how the online stopwatch and countdown timer work.
The Pomodoro Technique is a time management method that splits work into uninterrupted 25-minute focus blocks (each one called a "pomodoro"), followed by a short break after each block. It was developed in the late 1980s by Francesco Cirillo, who used a tomato-shaped kitchen timer — hence the name, from the Italian word for "tomato." The goal is to reduce procrastination and distraction by breaking large, overwhelming tasks into small, measurable chunks.
How many minutes should a pomodoro be? (the 25/5 rule)
Quick answerThe classic pomodoro is 25 minutes of focus + 5 minutes of break, known as the "25/5 rule." After every 4 pomodoros, a 15-30 minute long break follows. The duration isn't fixed: deep-work sessions may prefer 50/10 or 90/20, while shorter attention spans may prefer 15/3. This tool lets you customize the focus, short break, and long break durations down to the minute.
- Focus (25 min) — an uninterrupted block spent on a single task; silence your phone and notifications.
- Short break (5 min) — stand up, drink water, rest your eyes; step away from the screen.
- Long break (15-30 min) — a longer break after 4 rounds that refreshes your mind.
- Round/session counter — see how many pomodoros you've completed; a small but real motivation boost.
How do the online stopwatch and countdown timer work?
Quick answerThe stopwatch counts up from zero and records split times with the Lap button, automatically marking the fastest and slowest lap. The countdown timer counts down from a duration you enter and plays a sound alarm when it reaches zero. Both run in the browser with millisecond precision; remaining/elapsed time is shown on the progress ring and in the tab title.
Use the stopwatch to time workouts, presentation rehearsals, or game rounds; use the countdown timer for cooking, study sessions, breaks, or short meetings. Quick chips for 1, 3, 5, 10, and 25 minutes start the timer with a single tap.
How do you set a sound alarm while working?
Quick answerFor an alert after a set duration, enter the time on the Countdown tab; for an alert at a specific time of day, enter the target time (e.g. 3:30 PM) on the Alarm Clock tab and press Set. The sound is generated entirely with WebAudio — no external file, app, or internet connection needed. You can also enable browser notifications for a desktop alert while on another tab; the sound still plays even without that permission.
