Before a call you are dreading
Two minutes of box breathing between the calendar reminder and the meeting link.
Breathing
Breathing exercises where the stress happens
Nine rhythms, from a two-minute reset to the slow one that puts you to sleep. The circle leads, you follow, and the tab you were in is still there when you finish.

Nothing about this visit left your browser.
Time to wind down
Breathe with the circle until the screen lets go.
Rain over the page
Ambient sound, nothing blocked.
Look 20 feet away
Twenty seconds. Your eyes have been at this screen for two hours.
Three things today
Written this morning, still waiting.
Today you are the Learner
Every tab is a vote for who you are becoming.
Dark, without the mess
Images keep their colours. Already-dark sites are left alone.
25 on, 5 off
The rhythm runs itself; you stop watching the clock.
Warm after sunset
The page warms up in the evening instead of glowing at you.
Two minutes
In, hold, out — follow the circle and go back to work.

on
click the toggle — this is the real interface, not a screenshot
Every breathing app asks you to pick up your phone. The thing that made you tense is on the screen in front of you, and reaching for another screen is how a two-minute pause becomes twenty.
How it works
Two minutes, then back to the tab
The exercise runs over the page you are on. Nothing is blocked and nothing is lost.
01
Pick a rhythm
Box breathing to steady yourself, 4-7-8 to wind down, the physiological sigh when you need it to work in one cycle.
02
Follow the circle
It grows for the inhale and shrinks for the exhale, and each phase lasts exactly what the rhythm says — not a generic animation running at its own speed.
03
Finish and carry on
Time and completed cycles are both on screen. When the practice ends you land back on the same page.
What you get
What is in the nine rhythms
Box breathing, 4-4-4-4
Four counts in, hold, out, hold. The one taught for staying level under pressure.
pro
Relax, 2-2-4
Short cycle, long exhale. Free, and the one to start with.
free
4-7-8 for sleep
A long hold and a longer exhale — the rhythm people reach for at night.
pro
Coherent breathing, 5 and 5
Six cycles a minute, the pace where heartbeat and breath fall into step.
pro
The physiological sigh
A short top-up on the inhale and a long release. Works in a cycle or two.
pro
Reminders on a schedule
A breathing pause at 11:00 and 15:00 without you remembering it. Part of Pro.
pro
Common cases
When people actually use it
When a message lands badly
The physiological sigh takes the edge off in one or two cycles, which is faster than composing the reply you would regret.
Instead of the fourth coffee
Coherent breathing for two minutes does more for the afternoon than another cup.
At the end of the working day
4-7-8 marks the line between the day and the evening, still at the desk.
When you are already lying down
The same rhythms are inside Sleep mode, timed to the bedtime schedule.
Only on certain sites
Give the reminder its own list — the inbox, the ticket tracker — instead of every tab.
What breathing sends
Nothing about a session leaves your browser. Which rhythm you picked, how long you breathed and how many cycles you completed are counted on your device, the same as every other mode.

About Breathing
How is this different from breathing inside Zen or Sleep?
Those are long sessions with sound and a bedtime schedule around them. This is the exercise on its own: pick a rhythm, breathe for a couple of minutes, go back to the page.
Which rhythm is free?
Relax, 2-2-4. It is short, has no long holds and shows you what the mode does. The other eight come with Pro.
Do I need an account?
No. Install it and press the button.
How long should a session be?
Two minutes by default. One is over before it does much; five is long enough that people postpone it. You can set 1, 2, 3, 5 or 10.
Will it interrupt me on its own?
Only if you set a schedule, and scheduling is part of Pro. Starting it by hand is free and always yours to press.
The other eleven
They work together, not instead of each other
Breathing is one of twelve
It comes with blocking, focus sessions, screen time, dark mode and eye care — free.
