This document outlines the requirements for developing a mobile application. It will describe the functionality, usability, performance, security and design constraints. The application is being designed as a two-part project - the first is a requirements study and the second will be a working prototype. The document provides an overview of the application, describes the target users and business model, and lists references to comparable existing applications.
