SketchBook Pro: An easy to use drawing tool that bundles professional sketching options

Autodesk SketchBook is a practical drawing application that enables you to design various types of design and illustration projects using advanced sketching options.

There are numerous image editing functions that can be adjusted, such as brightness, contrast, color inversion, support for layers, crop, resize, and so on.

Moreover, Autodesk SketchBook includes a rich collection of brush types and drawing tools, including pencil, marker, ballpoint pen, airbrush, and others.

Since it was primarily designed for handheld devices, you can also customize the stylus responsiveness for each brush, and even create custom brushes with user-defined shape, size, opacity, texture and roundness.

Other features worth mentioning are the Symettry function which lets you create perfectly symmetrical designs, the Color Editor, and the Color Puck tool that lets you quickly select and adjust a color.
