Who Says? is a mobile app developed for QUT’s Principles of Interaction and UX Design unit (DXB110). Designed to support a healthy fast-food business focused on customisable, locally sourced salads, the app enhances the user experience by offering full customisation of ingredients, portion sizes, and dietary preferences. It tracks order history for quick reordering, suggests personalised combinations, and provides transparency about food provenance. With accessibility features like zoom and text-to-speech, Who Says? ensures an inclusive and seamless ordering experience, bridging the gap between ethical, sustainable fast food and digital convenience.
