Check out Cycles!
Cycles is a super-simple time and focus management utility for MacOS. It is SURE to make your life better immediately upon first use or your money-back…. GUARANTEED! (It’s free).
I made this because I wanted a easy way to break down my work-time into 20 minute chunks where I can focus entirely on one task. Open up Cycles and it displays a small 20 minute count-down timer in the corner of your screen. When time is up it displays an alert (including FREE bonus motivational quote). Act now and I’ll thrown in a settings window where you can adjust the timer length.
