The device position finder may be a stupid fun app but it displays the location of the device with an 'incredible accuracy'. No GPS, nor network connection network are necessary, thanks to a 'special' approach to locate the device. The application therefore works for iPhones as well as the iPod Touch. The highly sophisticated implementation and the unique locating experience make this FUN app particularly suitable for demonstration at the local pub. You will love it.

Only a fun-App, no deep use, no real functionality, but if you love senseless Apps than take this one!
