## What is Kumo RAIN?

Kumo RAIN is a quiet instrument for thinking, sleeping, and being still.

Most sound apps are loud — endless lists, blaring autoplay, one more thing demanding your attention. Kumo RAIN is the opposite. Open it, choose a sound, put the phone down. It’s built to be listened to, not looked at.

Launching with two sound worlds:

雨  RAIN — let it fall. Steady, soft, or heavy.
水  WATER — follow the stream.

More weather is on the way.

— BUILD YOUR OWN QUIET —
Layer sounds together and set each level by hand. Choose a texture for every layer. Save the feeling of a place you remember. No two evenings sound alike.

— DRIFT OFF —
A sleep timer fades gently to silence in 15 to 90 minutes. Fall asleep; the sound bows out on its own. Background and lock-screen playback keep it going while you rest.

— A CURATED INDEX, NOT A NOISE DUMP —
Every sound is chosen, named, and placed — Water, Earth, Air, Place. Quality over quantity, always.

— ON EVERY DEVICE —
Create a free account and your library, mixes, and sessions follow you everywhere.

— DESIGNED TO DISAPPEAR —
A calm, Japanese ink-wash aesthetic. Warm paper, deep ink, a single brush-stroke circle. Nothing blinks, nothing nags.

Made for people who want calm to think, sleep, or simply be still — designers and readers, parents, and anyone awake at 2am.

PRO — COMING SOON
A future subscription will unlock every sound and weekly new drops, unlimited saved mixes, lossless offline listening, home-screen widgets, and a sleep journal. Today, Kumo RAIN is free.

Turn it on. Let the room fill. Disappear for a while.
