Cell Phone Tracker - Lite (Android) 2.7.2
Play pranks on your naive friends by making them believe that you can track the location of their mobile phones in real-time via satellite
To use the app, simply type in your friend's number into the app and press Locate. The software will show you the coordinates on a map.
The trick is that in reality the app tracks the location of your phone. And since your friends will be standing next to you when you are performing the trick, they will think the application really works.
