As a rule thumb, the more popular a social network is the uglier, slower and more terrible its mobile app gets.
Facebook's app, for instance, has long been criticized for its battery hogginess, especially after it's been discovered that it's suspiciously circumventing Background App Refresh to continue running in the background when it should not.
That's where Social Square comes into play.
Formerly known as MySocial, this iPhone app by Chase Giles lets you browse Facebook, Twitter, Instagram, Google+ and Tumblr without having to worry about your iPhone's battery life.
