On the split screen you can see at the same time what the program code looks like when you create the patterns with shapes or what the pattern with shapes looks like when you create a program code.
The app deals intensively with the topic of "loops" because they have a special meaning when programming and creating patterns.
The app works best on the iPad because you can see two views at once and see how changes affect the different layers (pattern/programming). On iPhone, you only see one view at a time, but you can switch between views.
