This project case is about making a prototype of an interactive mobile application. Me and my team decided to make a simple online food ordering application. We named it Sliceya. Sliceya is a mobile application that provides a feature so users can buy desserts online. Users must register first if it is their first time using the app. After registering, users will be redirected to the home page and can explore all available pages and buy the desired desserts. The prototype was developed using Axure RP 9 Student Edition. The task flow and site map was also created before prototyping the mobile app.
