Autodesk has released the SketchBook Pro App for iPad, a new pro-level paint and drawing tool that it says is designed exclusively for the iPad, though it's based on the company's SketchBook Pro desktop software and its SketchBook Mobile iPhone app.

The SketchBook Pro App for iPad combines digital pencils, pens, markers and airbrushes with a Multi-Touch gesture-based user interface. Autodesk says that its geared for both occasional doodlers and professional illustrators, and uses the same paint engine as its desktop and mobile counterparts.

The SketchBook Pro App has a full-screen, 1024 x 768 workspace that works both horizonally and vertically. There are 75 brushes with customizable settings, including synthetic pressure sensitivity and brush modes for free sketching and creating straight lines, ellipses and rectangles.

The app supports six full-resolution layers per sketch with complete control over layer order, visibility and opacity. There's also a built-in, live news page that alerts artists to upcoming events and highlights featured artists and their SketchBook creations.

The SketchBook Pro App for iPad costs £4.99 including VAT and is available here at the iTunes App Store.

It will see competition from Adobe's free Ideas and the iPad version of Brushes.
