Work and break cycles with a round counter

How it works

A state machine advances work to short break unless the round is divisible by the selected cycle length, when it chooses long break; a completed break advances the round or resets it after the long break. performance.now measures each phase and Web Audio signals transitions.

• 25 minutes work, 5 minutes rest, 15 minutes long rest, and four rounds follow the familiar Pomodoro pattern but remain editable.
• Reset returns to work round one instead of retaining a partial cycle.

Worked example

											Work minutes: 25
Break minutes: 5
Long break minutes: 15
Rounds: 4
										

												Work 25 → Break 5 → Work 25 → Break 5 → Work 25 → Break 5 → Work 25 → Long break 15
											

When to use this

Writers separate drafting from rest, students group four work periods, and solo task queues make breaks visible.

Edge cases

• Skipping work advances to its break because skip means move to the next phase.
• Editing a length does not recreate time already elapsed inside a running phase.
• Background throttling can delay the display or chime even though phase elapsed time uses monotonic timestamps.
