Order Pizza is an iPhone application that allows users to order pizza from virtually any restaurant, using the iPhone's GPS to provide location-aware listings of nearby restaurants serving pizza. The app takes orders via the iPhone and then places a call to the restaurant, converting the order to text and reading it to the restaurant using Twilio's text-to-speech engine. The company behind Order Pizza plans to earn revenue by selling premium services to pizzerias, such as their own branded apps or additional menu options.
