Screaming Sounds Prank is a free horror game that will let you use your smartphone to simulate different kinds of horrifying noises, such as a head bumping against a wall, a scream, or a zombie attack. All you need is your voice.

To create a sound, simply speak the word that you want to hear, and the app will interpret your speech. Once you're finished, the app will play the sound, and you can even record your own voice and play it back to yourself.

In addition to the sounds, you can add music to the mix. Just click on the "Add Music" button, select the type of music you want to add, and choose the song you want to play. You can choose from a list of popular songs, or pick one from your own device.

After you've finished recording your voice, you can save the file. This will allow you to play the sound back later, if you want.

This app is perfect for those who want to scare their friends or scare themselves. It's also a good way to have fun and entertain your friends.
