This document describes the development of a new mobile notice board app called UNews that aims to improve upon the shortcomings of existing physical notice boards. The existing boards are described as unorganized, scattered, temporary, having fixed space and being crowded. The new UNews app is proposed to be mobile, organized, compact, permanent, secured, personalized with unlimited space. It will use a Django server backend with an Ajax-driven front-end for asynchronous data transfer without page reloads. JSON will be used for lightweight data interchange and an Android app will provide the mobile experience.
