For my thesis I created a mobile application for Windows Phone platform. Title of my thesis is Mobile application for parking and it is a system, which connects car parks in Slovenia. In application there are more than one functionalities, which help user with problem of finding right and free parking space, with information about them and data about city bus. The point of this application is that user can find car park based on location, where he can check prices and available free parking spaces. Application then navigates him to the car park he chose and saves his location so he knows where to return for his car. When he wants to leave, the application will calculate how much he needs to pay by how many hours he was there and how much is an hour.
