In BlueScanner you scan for Bluetooth devices (mobile phones with Bluetooth turned on) that are near by. You can use BlueScanner to spy on who are close. For every new Bluetooth device you find, you gain experience points that helps you level up and increase your global online ranking. You will also be able to see total number of players out there scanning for Bluetooth devices and the total number of found Bluetooth devices.
The application needs you to enable your Bluetooth in order to work. To find Bluetooth devices you need to get out among other people, in the street, in the subways etc.
You can also download the application directly by entering http://javaget.com/bluescan in the web browser of your phone.
God luck scanning!
