With this app you can send pranks to your friends. Just install it on both devices (On yours and of your friend's). On your friend's device tap on "Receive Pranks" to obtain a command ID, on your device tap on "Send Pranks" to access the control panel. Once in the control panel insert the ID obtained from your friend's device into the "Client ID" field and start sending pranks by tapping on different Pranks. Make sure to increase the volume to max on your friends device ;-)
