We originally posted about ProtoSketch late last year. This past April, ProtoSketch launched a major update with v 1.1. It is currently available in an iPad app and is optimized for iPad Pro. It enables you to create any design from logo to website and print. While the layering controls are a bit more like Adobe Illustrator, some Sketch users appear to be trying to incorporate it into their workflow.  According to their Twitter account, they are making attempts to support the Sketch file format.
