To design an intuitive and efficient web application, we first analyzed the structure of the Rewe website and examined navigation patterns in similar applications. To optimize the route-planning feature, we mapped the layout of a Rewe store in Landsberg, documenting shelf placements and product categories to create a clear in-app supermarket map. Key functionalities were initially developed as wireframes, forming the basis for structured prototypes in Adobe XD. The project name „Runaway“ emerged from a brainstorming session, symbolizing the optimized shopping routes generated for users. For development, we used PyCharm as our integrated development environment (IDE) and Flask as our framework. My contributions included defining core app functions, designing wireframes and prototypes, creating icons, implementing HTML and CSS, and developing the login page in Flask.
