FaceTime video chat has been around for years, but iOS 7 adds an audio-only option that's a prudent choice when you're not fit for public viewing. Sure, FaceTime's Apple-centric nature limits its usefulness in a multi-platform world -- you'll need another VoIP service such as Skype for audio calls to your Android- and Windows-lovin' friends and colleagues. (Of course, you could try a cellular call as well.) FaceTime Audio currently works only via Wi-Fi on the iPhone and iPad.
