50 Minute Timer
Fifty on, ten off.
50 Minute Timer ready. Press start to begin.
Each mark is one minute
Fifty minutes paired with a ten minute break is the long-form alternative to the pomodoro. It suits work that takes a while to get into and punishes you for stopping early.
What 50 minutes is good for
The 50/10 cycle
Fifty minutes of work, ten minutes away. Repeatable across a whole day without fraying.
A lecture
The academic hour, which has been fifty minutes for a very long time.
Sustained making
Writing, designing, building — anything where the first ten minutes are setup.
Questions
Why fifty rather than sixty?
The ten minutes are the point. A full hour of work followed by an immediate next hour is how people end up exhausted by two in the afternoon.
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.
