## What is Inku?

inku is a small, calm drawing surface. Drag one finger and real fluid ink swirls, blooms, and settles into the paper — no brushes, no layers, no menus. Every stroke also shapes its own generative sound, so drawing and listening happen as one gesture.

Press harder, or hold still, and both the ink and the sound respond — a firmer touch releases more ink and a fuller sound; resting in place lets a slow bloom keep breathing on its own.

WHAT'S INSIDE
• Real GPU fluid simulation — not a filter or a preset, an actual physics-based ink surface
• Generative sound built from how you move, not a looping soundtrack
• Nine ink palettes, from Indigo to Cherry Blossom
• Eight generative sounds, from a bright plucked tone to a slow ocean swell
• Sliders to shape the ink's own behaviour — turbulence, brush size, flow force, pressure response
• A soft haptic breath while you draw, on supported devices

Three palettes and two sounds are free to start. The rest unlock with a single one-time purchase — no subscription, ever.

inku works completely offline. Nothing you draw is saved, uploaded, or seen by anyone but you. No account, no analytics, no tracking of any kind.
