Guns!

Hear the sound of four different weapons.

This app allows you to choose among four different weapons a hear the sound they do when fired. Currently offers a shotgun, desert eagle, a submachine gun and a chainsaw. There are no animations, no info about the characteristics of each weapon, no nothing. Sound is awful and keeps ringing out for a long while after you shook the device.

There's an upgrade pack with more weapons. If you want to help the developer, go ahead. If you were looking for an app that simulates a weapon, look anywhere else. In fact, if you search enough you'll find apps that play with your phone camera and other fun stuff.
