This application uses your GPS to work out the speed of any moving object, Car ,Bus, Train. You can even use it to find out how fast you are walking, running or riding a bicycle.

It gives a reading

1:Kilo Meter Per Hour
2:Miles Per Hours
3:Meter Per Second

It displays your GPS latitudinal and longitudinal coordination. Also shows your Orientation using your phone compass reading.
This application uses less graphic in order to consume less battery power.

Important*
This Application is best suited for large screen mobile devices.
