gMeter is an application that turns the iPhone and iPod Touch into a vehicle performance computer. By using the onboard accelerometer in these devices, gMeter can measure forward and lateral g forces and use this data to compute acceleration, velocity, distance traveled, and engine power. gMeter is setup to compute performance for timed distance (1/4 mile or 400 meter), timed speed (0-60 mph or 0-100 km/h), or timed braking (60-0 mph or 100-0 km/h), and offers a hands-free automatic start feature (based on vehicle motion). gMeter also offers a full manual mode.
gMeter can display data and compute performance in US or metric units, and data from performance runs can be saved and e-mailed right from the device. The software has two calibration modes, and offers a correction to account for vehicle pitch under acceleration and deceleration. Engine power computations include inputs for drivetrain loss, rolling resistance, aerodynamic drag, and weather conditions.
What's New in This Release:
· Revised graphics. Performance improvements. Roll angle correction for lateral g. Increased fidelity of data export. Advanced data filter via post-processing. Option to reset advanced calibration. New PDF documentation. Fix for accelerometer timestep issue affecting some devices on iOS 4.
