Pomodoro Timer

The Pomodoro Timer implements the Pomodoro Technique, a time management method that alternates between focused work intervals and short breaks. By default, one cycle consists of 25 minutes of work followed by a 5-minute break; after every four cycles, a longer 15-minute break is triggered. All values are configurable.

To use it, click start to begin the countdown. At the end of each period, an audio signal alerts you to the transition, and the timer automatically switches to the next mode (work or break). A session counter tracks how many work cycles have been completed in the current session. You can pause, resume, or reset at any time, and adjust the work and break durations in settings.

The technique is especially useful for tasks requiring sustained concentration — studying for exams, programming, writing, design, and any intellectual work that suffers from distractions. The enforced alternation between focus and rest reduces mental fatigue, improves the quality of attention, and helps maintain a realistic estimate of time spent on each activity.

The tool runs entirely in the browser — no installation, no account, and no cost. The audio signal uses the Web Audio API without requiring external files. No data is sent to servers.
