Francesco Cirillo created the Pomodoro Technique to help him stay on task to increase focus and productivity; however users often complain that the constant timers either interrupt a good working session, or forces them to work through exhaustion and burnout.

You focus on one task and work until you need a break, and track the amount of time spent. At the end of the week, you have a better understanding of your most productive times, and which task delivers the highest flow time.
