When your phone is connected to the Wireless network, this app sends spoofing packets to all other devices and make then think that your phone is access point (or router). As a result, all the packets start flowing through your phone and then you can kick off them. This app will not disconnect them but only disable their Internet access and make them think that they are connected to a very slow Internet connection.
