Krita Sketch, a version of Krita for touch interfaces, has been released. Krita is a cross-platform sketching and painting application for the K Desktop Environment (KDE). It is a component of Calligra, KDE’s native Office and productivity suite. Krita has support for concept art, comics, and textures for rendering.

Krita Sketch was developed by team KDE and KO GmbH in partnership with Intel. It comes with the same set of features available on the desktop version: layers, filters, mirrored painting, powerful brush engine, brush presets, and lots more.
