The problem with classical Pomodoro is that we often finish our work early or the task takes longer than 25 minutes, resulting in interruptions by the alarm.
Flowmodor addresses this by offering flexibility: work x minutes, take x/5 minutes break. Flowmodor automatically calculate and set break timer for you based on your work duration. In this way you can stay in the flow state while maintaining the 5:1 work-break ratio.
