The document is a reflective diary of a student's four-week process of developing a mock travel app for York. In week one, the student created prototypes of a map, traffic updates, and parking locations. Some original ideas like a questionnaire were scrapped due to time constraints. In week two, the student replaced the questionnaire with a trail generator based on interests. In week three, the student added details to the traffic and parking sections. In week four, the student tested the app for bugs and gathered feedback by sending a screen recording to friends.
