Scream Machine is a fun app that you can use to play pranks on your friends and family. Arm the phone and place it in a strategic location. Enjoy the laughs when the unsuspecting party triggers a scary sound from your phone! Configure many options such as randomizing pitch and sound played when armed, delay between armed sound repeats, armed movement sensitivy, timed countdown seconds, and whether to fade the screen out when armed. Scream Machine also allows you to record your own scream or scary sound, save it, and then play it back when armed. Lure sounds can be played at specified intervals to make someone more likely to pick up your phone!

NEW trick page fools people into thinking they are taking an eye test. On the the third page a scary image will suddenly appear with a scream!

Try connecting your phone to speakers for a stronger effect!
