Bring designs to life digitally with Autodesk SketchBook Pro. Considered the industry standard, this pixel graphics software app is a professional-grade paint and drawing app. Offers a radial/pie-menu user interface with a complete set of sophisticated sketching and painting tools through a streamlined, intuitive interface. Transform your tablet into a powerful digital sketchbook. $4.99 for iOS and Android.
SketchBook Pro has an uncluttered interface, and painting and drawing tools such as pencils, markers, and brushes. By using the pressure-sensitive features of graphics tablets, tablet computers, and smartphones, it can help artists sketch and create effects similar to traditional materials.
Autodesk SketchBook Pro software also features a screenshot tool for annotation, allowing users to show content during a meeting and add notes as the content is reviewed. The previous/next buttons make it possible to create flipbooks or animations. The program supports layers with import and export of Photoshop (.psd) format. Other features include rulers, symmetry, the ability to customize brushes, create texture brushes, and rotate the canvas.
SketchBook Pro communities exist on Twitter, Facebook, and Autodesk's AREA online community.
