Welcome to gPC Official Webpage


What gPC is (also known as gMeter for the previous versions):

gPC (Performance Calculator based on g-forces) is a unique application able to transform any HTC Touch Diamond/Pro, HTC Touch Diamond2/Pro2, HTC Touch HD/HD2(LEO) or Samsung OMNIA (i900) device,  into a powerful vehicle performance calculator, using the onboard accelerometer in these devices.



  • Forward and lateral g forces measurements

  • Horsepower vehicle’s calculation using device's internal GPS receiver.

  • Advanced processing methods of all calculated values, including g-forces (m/s^2), angles, GPS data and calculated horsepower (HP), while being saved to a proper log file by the user.

  • 0 - 100 Km/h or 0 - 60 miles/h acceleration times calculations.

  • Calculation of time and horsepower for 0 - 402 meter or 1/4 of mile acceleration times, while in dragster mode.

  • Log opportunity of any of the max horsepower, g-forces or angles values.

  • Drawing 'circuit’ capability according to the longitude and latitude values measured by the internal GPS receiver.

  • Speed and horsepower graphs utility using the appropriate user’s log files.


Important Notice:

Before using the application, user’s device needs to be placed onto the vehicle for necessary gPC’s calibration according to its position, while vehicle is at rest mode on the surface level.



  • HTC Touch Diamond/Pro, HTC Touch Diamond2/Pro2, HTC Touch HD/HD2(LEO) or Samsung OMNIA (i900)

  • Microsoft .NET Compact Framework 3.5 (download .cab file here)

Please, help me to improve the program:
As the gPC is a research project, anyone who wants to donate more than 15€/device by using PayPal, can get a license* for the full version of the gPC.
The donators who want a second or a third license, can get it with 7.5€/device (contact support for more details)

Please donate if you believe my time and efforts are worth it. Thanks!
