Pomodoro timer's were created to support the time management method of the Pomodoro Technique. The idea is to break down a project into specific units of time, spaced by short breaks. There are six guidelines: decide the task, set your timer, work on the task, put a checkmark on a piece of paper, take a small break and set the timer again, after you do four cycles of the 'pomodoro' you can take a longer break.
