Siri is an application built into certain iOS devices. It takes what the user says to it and responds to it by web services. At first, Siri was an app in the App Store, but it was gotten by Apple on April 28, 2010.  Siri has been supported by all devices since the iPhone 4S, and is in iOS 5 devices other than the third generation iPad. When iOS 6 came out, the third generation iPad got Siri.
