FaceTime is a video calling service Apple created for customers of its own devices. It launched alongside the iPhone 4 in 2010 for iPhone-to-iPhone video calling, but now anyone with iPhone, iPod Touch, iPad, or Mac can FaceTime anyone else with one of these devices. While Apple has not released a FaceTime app for Android, there are alternative ways to video chat with someone on an Android phone.
Video Call from iPhone to Android Phone with Skype
One of the most popular apps for chatting and making audio or video calls is Skype. Skype is available on multiple platforms like iOS, Android and Windows Phone -- and allows for cross-platform video calling unlike FaceTime. An iPhone user can download the free app from the App Store, while an Android user can download it for free from Google Play. Sign in with an existing account or tap "Create Account" and fill out the form to get started. When you arrive on the Contacts page, tap the Add Friend icon and tap "Search Skype Directory" to type in your friend's username. Tap it, then tap "Video Call" to initialize the call.
