Pomodoro
Short blocks with the break built in, so you stop before you are empty rather than after. A block cannot be halved; that is the rule the whole thing rests on.
Methods
The boards in Plan say what to work on. This is the part that asks how: four ways of getting started and staying with it, each a way of buying attention for a fixed length of time.

The hard part of a task is almost never the task. It is the beginning, and a beginning that only costs five minutes is not worth avoiding.
A break, a meeting, an exam paper. Keeps nothing and asks nothing.
An hour on, an hour off. The hour starts it, and the hour arrives whether or not you felt ready; a pace you can hold for ten hours.
None of these make the work easier. They make it small enough to begin, a fixed block, an hour, five minutes, so the decision in front of you is one you can actually make.
A run is anchored to the wall clock. Lock the phone or leave for twenty minutes and the count is still right when you come back, and the phone tells you when the block is up.
Starting a second one closes the first and records what it did. Whatever is running shows at the top of the screen, so a run left behind a locked screen is never lost.
Pomodoros and odd/even hours are recorded against the day. The five-minute rule and the plain timer keep nothing; they are for getting moving, not for the record.
