Bold strokes, Grainy touch.

Jul 01, 2025

Creative app and videogame producers IORAMA are pleased to announce the release of Graintouch, a new iOS drawing app with the soul of print. Inspired by Risograph™ aesthetics, Graintouch lets you layer, blend, and create with the warmth of real ink-right on your screen.

Graintouch's Bool Brush is a bold, organic vector brush that stacks colors like ink on paper. Blend, overlap, knockout and build rich textures with effortless strokes.

The app features a full print simulation, allowing artists to see their artwork as if it just rolled off a risograph. Implement offset imperfections, layered tints, and see your art with the charm of real ink —without the mess.

Graintouch features a minimal UI: nothing in your way, just pure drawing. A clean, focused space where tools feel like an extension of your hand.

With a playful palette of 18 handpicked inks, straight from the riso universe, Graintouch users have meaningful constraints that can spark creativity-just like mixing real inks on a print run.

Graintouch is available now on the App Store, at a price of $9.99 USD.
