8 Hour Timer
A full working day, or a full night.
8 Hour Timer ready. Press start to begin.
Each mark is 15 minutes
Eight hours is a working day and a night's sleep — the two blocks the rest of the day is arranged around.
What eight hours is good for
A working day
A shift with a visible end, rather than one that finishes when you run out.
A long ferment or charge
Dough overnight, or anything that needs to be left until morning.
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.
Will it survive the tab being closed?
No. The countdown lives in the page, so closing the tab ends it. For something running this long, a phone alarm is the more reliable tool — which is part of why Porotimer exists as an app.
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.
