MilesPerGallon is a very simple mobile application that I built for the Windows Phone platform that simply allows you to maintain a list of cars in your household, and enter fill-up information whenever you put petrol in.
Using this data, the application shows you your average miles per gallon since the last fill-up, and since you started keeping records, for each car.
The application was more of a technical exercise than anything really useful, but taught me the basics of XAML, Windows Mobile File I/O, Mobile Application LifeCycle and also deployment to both devices and the Windows Store.
