The 52/17 timer: 52 minutes of focused work, a 17-minute break, repeated for four rounds. The numbers come from DeskTime, a time-tracking company that found its most productive users worked for about 52 minutes and then rested for about 17 — a longer rhythm than the classic Pomodoro, built for work that takes a while to get into.
The long focus block is the point: deep work, writing, coding, or study where stopping every 25 minutes would break your train of thought. The 17-minute break is long enough to genuinely reset before the next round. Press start to run all four blocks, or open the editor to change the lengths and rounds.
The classic Pomodoro — 25 minutes of focus, a 5-minute break, four rounds.
A longer study rhythm — 45 minutes of focus, a 15-minute break, four rounds.
Study, then one episode — 40 minutes of focus, a 20-minute break, four rounds.
