What it is: Shots is all about popping selfies and sharing them within the app's social network -- in other words, it's the most self-absorbed app on this list. While you can't leave comments on the selfies, Shots does let its users send direct messages to one another, so there is an element of interaction beyond just "Here's my face, look at my face." Plus, it's got an official list of influential users that include Justin Bieber and Floyd Mayweather. How can you lose?!
Our verdict: Obviously, this app's usefulness hinges on how tight your selfie game is, or you even having a selfie game for that matter. Seeing photos of attractive people's faces, though, would definitely have been a pick-me-up during slow school days.
