2 Hour Timer
Two hours, bounded.
2 Hour Timer ready. Press start to begin.
Each mark is five minutes
Two hours is an exam, a film, or a morning's work. It is long enough that you should plan a break inside it rather than hope for one.
What two hours is good for
An exam or a mock
The length most papers are set at, run under the same conditions.
A morning block
A whole session, with a break somewhere in the middle.
Parking and appointments
A limit worth being reminded of before it expires rather than after.
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.
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.
