The document describes concepts for a Harry Potter themed app that would function like the Marauder's Map from the books. It would include pages for the app logo, title screen upon opening, a loading screen, an options menu to select the map or photo upload pages, the map itself showing tourist locations in York linked to Harry Potter characters or themes, example information pages for each location, and a photo upload page. The app aims to be educational and fun for Harry Potter fans by connecting real world places to the fictional world.
