Application prototyping tool

A computer system for generating functional prototype applications in different platforms without rewriting code for each different platform comprising:

• a hardware memory device that stores program instructions;
• and
• a processor that executes the program instructions and causes the computer system to:
• design, modify, and update design layouts for prototype applications using a library of native design elements, which are visually rendered with its related functionality in a relative layout on a canvas of different platforms;
• navigate between different pages of the prototype application;
• publish the design layouts for the prototype applications with the native design elements;
• and
• associate comments with specific native design elements for which it pertains and share the comments amongst different computing devices including a native computing device which renders the native device elements as a functional prototype application.
