This document describes a proposed mobile application called the I Smart Solution app. The app aims to help consumers find goods for sale at retailers at reasonable prices after taxes by allowing retailers to post their prices and consumers to search for the lowest prices. It would allow retailers to register and update their business information and product offers. Consumers could search for products and see contact details of retailers offering the lowest prices. The proposed app is intended to increase transparency and trust between retailers and consumers in pricing goods. It was designed using an incremental Rapid Application Development model to allow for iterative testing and improvements.
