What Does FaceTime Mean?
FaceTime is a video chat application developed by Apple and supported by devices such as iPhone4 and above, 4th generation iPod touch or above, iPad2 or above running on Apple iOS and Macintosh computers that run Mac OS X 10.6.6 or above. Making use of front-facing and rear-facing cameras in the devices, it was initially available only on Wi-Fi connections, but was made available over mobile networks as well for iPhones. FaceTime allows Apple users to make free calls to other Apple users over a cellular connection or Wi-Fi.
Techopedia Explains FaceTime
FaceTime allows only connections between Apple devices and supports only one-to-one video services. It is highly incompatible with non-Apple devices or with other video calling applications and services. Although in iPhone FaceTime is bundled into phone applications, it is a separate application for all other Apple devices like Mac, iPad or iPod touch. As a dialer is absent in these devices, an Apple ID and an email ID are required for FaceTime on Mac, iPad and iPod touch.
