This article explains how to download FaceTime for iOS devices and Mac computers. This information applies to iOS devices running iOS 5 or later, and to Macs running OS X 10.6 or later.
Set up Facetime on Mac
Apple FaceTime works on most Apple devices. You usually don’t need to download FaceTime for iPhone or iPad, as it comes pre-installed on every iOS device running iOS 5 or later.
If you deleted FaceTime from your iOS device, you can redownload the app from the App Store for free and then reinstall it.
If FaceTime isn’t working as expected on your device, it may have been disabled using the Restrictions feature, which lets you hide apps.
