What is GT?

• GT is a program for S60 mobile phones. It uses the phone's internal GPS receiver or a Bluetooth GPS receiver to measure top speed and acceleration (0-100 km/h and 0-400 m, or 0-60 mph and quarter mile, or any given speed range and distance). With GT you can measure the performance of your car, motorcycle or any other vehicle.

• GT is also useful for navigation, giving direction and distance to any set destination.
