According to the SketchBook Mobile FAQ:

Q: Does SketchBook Mobile work with SketchBook Pro?
A: Content that is created in Autodesk SketchBook Mobile can be saved as a picture and opened in SketchBook Pro. As a result, artists, designers and anyone who likes to sketch or create artwork can create a drawing at any time with SketchBook Mobile, and continue building on their idea in SketchBook Pro.

The key to SketchBook Mobile is that it uses the same engine as SketchBook Pro. This means you get the same look and results from brush strokes. Currently, you can share flattened images with SketchBook Pro and continue building on the image. The results are seamless.
