NotchMindThe Pomodoro technique, created by Francesco Cirillo, is simple: work for 25 minutes, take a 5-minute break, and after four rounds take a longer one. The timer is the whole trick, so it helps to have one you can see.
With the Clock app
Open Clock, choose Timers, set 25 minutes and start. When it ends, set 5 minutes for the break. Saved timers make this two clicks.
With Siri
“Hey Siri, set a timer for 25 minutes.” Then “set a timer for 5 minutes” at the break.
Silence distractions
Turn on a Focus, such as Do Not Disturb, for the 25 minutes so notifications don’t break the session. See Focus on a Mac.
A timer you can always see
The hardest part is resisting checking how long is left. NotchMind, which I make, keeps the countdown in the MacBook notch, so a glance up is enough. Drag the ruler on the Timer page to 25, start it, and the alarm plays when it’s time for a break. Timers you start in Clock or with Siri show in the notch too. See set a timer from the notch.
Make it stick
Write down what you’ll do before each round, and stop the moment the timer rings, even mid-sentence. It’s easier to start the next round when you know where you left off.
