Fōkasu Is A Simple Timer Based On The Ideal 52/17 Productivity Schedule 

Time-tracking app company DeskTime found that the most productive people worked for 52 minutes straight followed by a 17 minute break. If you’d like to try this routine yourself, Fōkasu is the easiest way to time yourself.

Just head to the site, and click the Start button. The timer will count down the 52 minutes, give you an upbeat music alert and then count down the 17 minutes.

You could also use other timers for this, such as flexible Pomodoro timer Marina Timer, but Fōkasu already has the 52/17 ratio built in.
