About this 25-minute timer
A one-click 25-minute countdown, most often used for a classic Pomodoro focus session, a single-topic work sprint, or a guided meditation. It runs in your browser and rings when it reaches zero.
The Pomodoro Technique
Twenty-five minutes is one 'pomodoro' — the core unit of the Pomodoro Technique developed by Francesco Cirillo in the late 1980s. You work for 25 minutes with zero interruptions, then take a 5-minute break. After four pomodoros you take a longer break of 15-30 minutes. The point isn't the exact number; it's that a short, defined, uninterruptible block makes starting easy and distraction expensive.

Tips for using a 25-minute timer
- Write down what you'll work on before you start. A pomodoro spent deciding what to do is a wasted one.
- If you get interrupted, the technique says the pomodoro is void — that rule is what makes people defend their time.
- Take the 5-minute break properly and away from the screen. It's part of the method, not optional.
- After four cycles take a longer 15-30 minute break to actually recover.
