What is the name of Apple's video calling software?

Apple’s video calling software is FaceTime. It is Apple’s proprietary videotelephony service for making video and audio calls across supported Apple devices.

FaceTime debuted on the iPhone 4 in 2010 with iOS 4 and later arrived on the Mac in 2011. It was designed around Apple’s front-facing cameras and tight integration with Apple IDs and phone numbers, making contacts easy to reach from the Phone, Contacts, and FaceTime apps.

A common mix-up is assuming FaceTime is simply Apple’s version of Skype or Zoom. Unlike those services, FaceTime was originally limited to Apple hardware, although Apple later allowed Android and Windows users to join calls through web links. Group video calling arrived with iOS 12 and supports up to 32 participants.

FaceTime is also distinct from iMessage: iMessage handles text, photo, and video messages, while FaceTime is primarily for live calls.
