StitchSketch is a perfect way to draw charts or pixel art. On the iPad I could use a stylus which blew the computer out of the water immediately. I imagine this format would work great for drawing icons and favicons too.
The app ui design is very much desktop computer inspired. It works well for an app with such powerful functionality. Nothing is dumbed down for mobile at all.
I was able to make a chart then save as to make multiple versions and then modify each version slightly. I could export each version as an image to my photos app then swipe through them to compare. Perfect!
