Breathing Timer

A circle that grows as you breathe in and shrinks as you breathe out, with a count in the middle. Four seconds each phase by default — box breathing.

Press F for fullscreen, Esc to exit.

Breathing patterns you can follow without counting

Box breathing is four seconds in, four held, four out, four held empty. It is used by people who need to steady themselves quickly, and it works partly because counting occupies the part of your attention that would otherwise be busy.

Following a shape is easier than counting, which is the whole reason for a pacer. The circle uses a smoothstep rather than a linear ramp, because a breath slows as it approaches the top and the bottom — a linearly growing circle feels subtly wrong to follow in a way people notice without being able to say why.

  • Box breathing — four, four, four, four
  • 4-7-8 — in for four, hold seven, out for eight, no hold
  • Coherent breathing — in for five, out for five, no holds
  • Any pattern you have been given by someone who knows your situation

Setting up 4-7-8 or any other pattern

All four phases are set independently, and holds can be zero. For 4-7-8, set four in, seven hold, eight out and zero hold empty. For coherent breathing, five and five with both holds at zero.

Your pattern goes into the address bar, so whichever one you have been shown is a bookmark rather than four sliders to set each time.

Using the breathing timer

Press F for fullscreen so the circle is the only thing on the display, and follow it. The number in the middle counts down the current phase.

If you feel light-headed, stop. Extended or forceful breathing exercises are not for everyone and are not something a web page can supervise — if a pattern was recommended to you by a professional, follow theirs rather than ours.

Questions

What is box breathing?

Four seconds in, four held, four out, four held empty — a square, hence the name. It is the default here and is the most commonly taught pattern for steadying yourself quickly.

Can I set the 4-7-8 pattern?

Yes: four in, seven hold, eight out, zero hold empty. All four phases are independent and holds can be set to zero.

Is the breathing timer free?

Yes — free, no account, no download, no limit. It runs entirely in your browser, so it keeps working if the connection drops.

Does it make a sound when it finishes?

No. Nothing on this site plays audio. The screen changes colour and flashes instead, which is what works on a muted display at the front of a room — and it will not startle anyone.

Can I save my settings?

They are already saved — in the address bar. Every change is written into the URL, so bookmarking the page keeps the timer exactly as you configured it, and pasting the link gives someone else the same one.
