Is Pomodoro a concept? Who proposed it?

Pomodoro is a working method. 25 minutes of work and 5 minutes of rest are counted as one Pomodoro. The higher the number of Pomodoros completed in a day, the higher the work efficiency will be. The 25-minute work period requires us to devote ourselves to work or study, and then relieve stress for 5 minutes. This working method was proposed by Francisco Cirillo, because this person did not study often, and then he came up with this learning method. You may not be able to grasp the time well when you first use it. You can use Screen Time Assistant to check.
