I want to say Snack has nothing to do with react-sketchapp, but unfortunately they do share a couple of things. The developer/user of both tools will write code that is largely compatible with each other, basically a shared subset of react-native. Then, there's the whole confusion with the name Sketch. Snack used to be called Sketch. react-sketchapp uses "Sketch.app" as a rendering engine and editing interface. "Sketch.app" is basically the next program in the workflow for the user of react-sketchapp.
