A private place to pause

A little quiet when you need it.

Short, gentle exercises for moments when anxiety, shame, anger, resentment, or overwhelm feels hard to hold. Begin without an account, an explanation, or anything to get right.

For the moment you’re in

Begin wherever you are.

If you know what might help, go straight there. If you do not, choose what feels loudest and kū-on will offer one small place to start.

Explore at your pace

Five small places to begin.

Each offers a different kind of support. Go straight to what feels useful, or simply notice what draws you in.

01 · Rhythm

Breathe

Follow a simple rhythm when your body is running fast.

02 · Senses

Ground

Bring your attention back to what is here around you.

03 · Body

Settle

Release some of the tension your body is carrying.

04 · Release

Let go

Put down what you are carrying in words that are never saved or sent.

05 · Reflect

Untangle

Work gently through shame or guilt without turning yourself into the punishment.

A quieter next minute

See how little it asks of you.

No tutorial to finish. No progress to maintain. Choose a path, follow one gentle prompt, and leave whenever you want.

Designed to ask very little

Nothing to prove. Nothing to maintain.

Four quiet promises shape everything inside kū-on.

01 · Begin

Open and begin

No account or setup is required. You do not need to name the feeling perfectly before you start.

02 · Yours

Private by default

What you write in Let go is not saved, uploaded, or sent. kū-on only remembers simple preferences, such as audio settings, on this device.

03 · Enough

No performance

No scores, streaks, or pressure to continue. Stopping after one breath is still using the app as intended.

04 · Close

Ready offline

After your first visit, the current exercises and audio remain available without a connection.

Why it exists

“I made kū-on for the moments when I needed help before I could explain what was wrong.”

I wanted something I could open immediately, use without preparation, and leave without turning it into another obligation. The aim is deliberately small: help make the next few minutes feel more manageable.

A personal project

Keep it close

Install kū-on in a few taps.

Add it to your home screen for a quieter, full-screen experience. After your first visit, the current exercises and audio can be used offline.

Open the app to install
  1. Open kū-on in Safari.
  2. Tap the Share button.
  3. Choose “Add to Home Screen,” then confirm.

Installation is optional. kū-on continues to work in an ordinary browser tab.

空穏kū-on · roughly “koo-on”

The name

The name started with a feeling.

kū-on is a coined name, written symbolically as 空穏. It is not an established Japanese word. The characters were chosen for the ideas they hold here.

空 · kūSky, space, or emptiness
穏 · onCalm, gentle, or peaceful

Together, they suggest a clear, calm sky and the quiet space kū-on was built to hold.

Take only what helps

You do not have to solve everything right now.

Use one exercise, stay for a few minutes, or leave whenever you want.
