30 Second Timer
Half a minute, held.
30 Second Timer ready. Press start to begin.
Each mark is one second
Thirty seconds is the length of a plank most people can actually hold, the time hands need under water to get clean, and about as long as anyone will listen to an unprompted explanation.
What 30 seconds is good for
A held position
Planks, wall sits, and the parts of a stretch where watching a clock is the only thing that keeps you honest.
Rest between sets
Short enough to keep the heart rate up, long enough to make the next set possible.
Questions
Will it make a sound when it finishes?
Yes — an alarm rings when the countdown reaches zero. The countdown also turns red and the tab title changes to "Time's up", so the end is visible as well as audible.
The hard part isn’t the timer
This page counts down, and that is all it does. Porotimer handles the part that decides whether the session actually works.
Lock away what breaks focus
Choose the apps you're allowed for the session. Porotimer puts everything else behind a wall until the timer ends — which is the one thing a page in a browser tab can never do.

Breaks that actually rest you
A calm scene and a breathing guide when the sprint ends, instead of five minutes of scrolling. You come back settled rather than scattered.

Every sprint and break laid out in order. The day becomes something you can look back on, rather than something you try to remember.
