gMeter is an Pocket PC Freeware that turns the HTC Touch Diamond/Pro or Touch HD into vehicle performance computers, by using the onboard accelerometer in these devices.

gMeter can measure forward and lateral g forces and it can calculate the Horsepower of a vehicle (wheels or engine), using the device’s internal GPS. All the values, including the g-forces (m/s^2), angles, GPS data and calculated horsepower (HP), can be saved to a log file, for furthermore processing. It can also calculate the 0 – 100 Km/h or 0 – 60 miles/h acceleration time. In dragster mode, the application can calculate the time and the horsepower for 0 – 402 meter or 1/4 of mile acceleration. Also, the gMeter can keep the max horsepower and the max values of g-forces and angles. The gMeter can draw the ‘circuit’ according to the longitude and latitude values measured by the internal GPS. gMeter can also create speed and horsepower graphs using the log files.

The device needs to be placed in a vehicle and gMeter needs to be calibrated for position, with the vehicle at rest on a level surface.

gMeter is new software for accelerometer equipped Windows Mobile smartphones designed to be used in cars to measure forward and lateral G-Forces. By using the onboard accelerometer in these devices, gMeter can measure forward and lateral g forces. Still in the early stages but looks very promising.

Future updates will include

• GPS speed, wrong conversion (fixed in new version)
• g-force graphs
• sensors values
• calculated horsepower
