75/15 Pomodoro Timer
75 minutes of focus, 15 minutes of break. 75/15 is a marathon block — for ultradian deep work, exam prep, and one-sitting projects.
Who should use 75/15
75/15 matches your body's ultradian rhythm. Use it for the deepest one or two blocks of your day — architecture, exam-day study, the hardest piece of a project.
