15 Minute Timer
A quarter of an hour, boxed in.
15 Minute Timer ready. Press start to begin.
Each mark is one minute
Fifteen minutes is the standard stand-up, the standard power nap, and the standard first pass at anything you have been putting off. It is the smallest block that still feels like real work rather than a gesture.
What 15 minutes is good for
A stand-up
The meeting length that stays a meeting. Past this it becomes a discussion.
A first pass
Enough to find out what a task actually involves, which is usually why it was being avoided.
A power nap
Short enough to wake up from cleanly, before the deep sleep that leaves you worse off.
A long break
The longer pause after a few pomodoros, when five minutes is not enough.
Questions
Is fifteen minutes long enough to get anything done?
For finishing, rarely. For starting, almost always — and starting is the part most tasks are stuck on.
Is it a good nap length?
It is one of the two lengths that work. Fifteen to twenty minutes wakes you before deep sleep; ninety completes a full cycle. The stretch in between is where people wake up groggy.
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.
Does the timer keep running if I switch tabs?
Yes. The countdown runs from a real timestamp rather than counting frames, so it stays accurate in a background tab, and the remaining time shows in the tab title.
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.
