Name: Google+ Hangouts
Compatibility: Compatible with iPhone, iPod touch and iPad. Requires iOS 4.3 or later. Android.
The updated Google+ app has resulted in a simpler format and seemingly more reliable Hangout video chat option. Miss the days you used to watch a film together? Never fear. Place the phone next to you, connect with your partner, stick the film on and you're away -- but of course, you'll need a reliable Internet connection.
Instant messaging is also a feature of Hangouts, and if you fancy tagging some of your friends along, the video chat now supports up to ten people talking simultaneously -- which is an option that makes it unique in relation to Skype or Facetime.
