- Alternative form of face time.
Apple's video and phone calling application for the iPhone, iPad, iPod touch and Mac. Similar in function to Microsoft's Skype, FaceTime works only on Apple products, whereas Skype runs on every major computing platform, desktop and mobile. FaceTime was introduced with the iPhone 4 in 2010 as a video calling service over Wi-Fi to the Internet. As of iOS 6 in 2012, video calls can also be made over the carrier's 3G/4G cellular network, using up data plan bytes as with all cellular Internet connections. In 2013, voice was added (see FaceTime Audio).
