A "Make your own pizza" app.
The idea is to have a kitchen-like interface which would allow the user to feel like they are more in control of the pizza making process, be it manual size selection, ingredients selection, or simply the baking timer - its all in their hands. In three easy steps, the user will have their pizza ordered.
The application would also allow the selection from the predefined menu if user doesn't feel like making their own pizza, as well as a history list for re-ordering a previously created pizza.
