Mobile applications have a lot of unique challenges during the development process. One of them is monolith architecture that can’t be skipped even for large Mobile Enterprise applications. Software engineer should keep mind the whole source code structure to be effective. This article will introduce an approach to Rapid Software Design that allows to make a working documentation related to code and understandable by all team members. Rapid Software Design is suitable for Waterfall/Agile processes of developing applications with graphical user interface (web, mobile, desktop, embedded) and initially was created for mobile projects. This article contains only the description of User Interface related documentation despite the whole Rapid Software Design also covering the usage of architecture patterns, business logic, services, features of mobile operation systems and writing automated tests
