FaceTime
A video telephone / video chat service somewhat similar to Skype and Google Hangouts that makes it possible to conduct one-on-one video calls between newer Apple iPhone, iPad, iPod touch and Mac notebooks and desktops. Apple’s FaceTime service is free to use but does require an Apple ID and a Wi-Fi connection, although future versions of FaceTime may also work over 3G and/or 4G connections, and several apps are currently available that make FaceTime over a 3G connection possible on a jailbroken iPhone.
FaceTime first debuted in the second half of 2010 on the iPhone 4, and currently supports the iPhone 4 and later, iPad 2 and later, the fourth generation iPod touch and later, and Macs with Mac OS X Snow Leopard (v10.6.6) and later installed. Some FaceTime features, like 720p resolution, are only available on certain platforms such as newer MacBook Pros and iMacs.
