The FaceTime application is included automatically on a Macintosh computer, iPod Touch, iPad or iPhone.

Once a FaceTime session is initiated, the user can choose the front camera for a face-to-face chat with family or friends, or the back camera can be chosen, which shows the person's surroundings. FaceTime can also be opened by voice commands on an iOS device that has a Siri subscription. The user simply tells Siri "FaceTime with Dad," and is automatically connected to a FaceTime session with the "Dad" contact that is in the iOS device.
