The workflow I am proposing should be used to prototype around some functionality. What I’m trying to show is how to do this without having to worry about making it look decent. The application that we end up with is real, so it can be expanded upon until you have you completed application.

InVision is great for showing stakeholders and developers a “walk through” of an application, but it doesn’t actually produce a working prototype so it wouldn’t be used for that purpose.
