Love this app! It’s the perfect reductionist version of a digital sketchbook. Much like pen on paper in a physical sketchbook, this app offers a simple record of your ideas without the frills. Archive the book when you’re done and you have an unalterable account of your ideas, warts and all.

Needs features

How about an undo button? Can’t figure out how to delete a sketch???!

Developer Response ,

Robby, thank you for your feedback. Undo capabilities is indeed something we thought of. Initially, our vision for this app is a sketch book implementation with minimal user interactions, limiting it almost exclusively to drawing and page turning - much like what one would do with an actual sketch pad.

We decided to implement Undo beginning with version 1.2.5, by enabling it through the menu options button.

The latest version is 1.2.6, please give it a try and consider a new rating.

Thank you.
