4 Minute Timer
The length of a full Tabata.
4 Minute Timer ready. Press start to begin.
Each mark is 15 seconds
Four minutes is one complete Tabata: eight rounds of twenty seconds on and ten seconds off. It is the shortest interval protocol with real evidence behind it, and the only workout that is genuinely over before the excuses arrive.
What four minutes is good for
One Tabata
Eight rounds, twenty on and ten off. If you want the rounds counted for you, use the Tabata timer instead.
A hard reset
Long enough to change how you feel, short enough to do between meetings.
Questions
Is this the same as a Tabata timer?
It counts the same four minutes, but as one block rather than eight intervals. For the twenty-on, ten-off rounds with cues between them, use the dedicated Tabata timer.
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.
