## What is Sumi?

Prop your phone against something on your desk, and it becomes a painting — a sumi-e landscape, quietly alive. The waterfall falls. Mist drifts between the pines. Evening comes on slowly.

On the train. Between two meetings. In the five minutes before sleep.
Open it and a quiet mountain is there.
Nothing to do. Nothing to finish.
Just the sound of water, and the mist.

This is not a video in a browser.
No ads, no playlist, no chrome around the edges —
ink from one edge of the screen to the other.
Touch the water and it answers under your fingertip.
Set the sleep timer and the painting falls asleep with you.

There is nothing here that asks anything of you.
No streaks. No lessons. No notifications.
Just a painting of the kind that has been settling people's minds
for five hundred years.

A framed print costs forty dollars, and it never moves.
Sumi is $5.99, once.
No ads. No tracking. No subscription.
Buy it once and it is yours — including every painting added later.

—

FIVE PAINTINGS
Falling Water · Rain at the Pavilion · Moonlit Bamboo · Fuji over the Waves · Koi in the Stream
The first is free. The rest unlock together, once.

DAY, DUSK, NIGHT
Each painting shifts with the hour, or stays where you put it.

SOUND, SYNTHESIZED
Water, rain, wind and waves are generated on your device — not recordings.
Turn it off entirely if you prefer the silence.

SLEEP TIMER
The painting dims and the sound fades. Nothing wakes you.

NOTHING COLLECTED
No accounts, no ads, no tracking, no analytics, no third-party SDKs.
Your settings stay on this device.
