Questions for a high school project

Hello, My name is Clara. I am a student from Terrassa, a city near Barcelona in Spain. I am doing a project for the high school with a classmate. We are writing you because our project is about this app, Geoworld. We would like to ask some questions about the app in order to improve our project. We would like to know what is the main goal of the app and in what way it uses geography and the Global Positioning System (the localization coordinates) to work. Thank you very much in advance for your help. Best regards, Clara and Aina
