How to use this timer
Pick one task, choose a length, and start. 25/5 is the classic Pomodoro cadence and the easiest way to begin on a bad day. 50/10 suits deep work once you are warm. 90/15 matches a natural attention cycle for writing and research. When the ring finishes, actually stand up for the break.
