Simulator Laser 3D Joke is a joke app that makes it seem like you're using a laser on your Android. The app OBVIOUSLY won't make a laser come out of your Android device nor do anything of the sort. All the app does is simulate a laser on your device's screen.
Simulator Laser 3D Joke is one of those apps that might be fun for a short period of time ... although it also might disappoint users who expect more out of it.
