Not everyone is into the Google+ social network but for those who are this app is a wonderful way to work with it.
It presents the current news feed in a gorgeous magazine layout that makes working with Google+ a lot of fun. I admit I never used Google+ much until getting this app.
The Google Hangouts feature is particurlarly useful on the Nexus 7 as it allows video chatting with up to 9 friends at once.
