Accelerometer Pro

This app shows you the components of the acceleration vector, as magnitude and direction, in all planes. The primary components of the acceleration vector (along the X,Y, and Z axes) are continuously read from your mobile device's sensor. The X, Y, and Z orientation axes relative to the device remain constant, as the planes they form. Fast algorithms combine these components and calculate the direction and magnitude of the acceleration vector in each of these planes: XY, XZ, and ZY. For example, if you hold your phone in a vertical position, the gravitational acceleration vector in the XY-plane must have a 270-degree inclination and a magnitude of 9.81m/s2.

Main features

- three sensors can be selected and tested: Gravity, Acceleration and Linear acceleration
- the vertical resolution of the graph can be automatically adjusted
- the Maximum and the Average value of acceleration are continuously displayed
- 'Start/Stop' and 'Select the plane' buttons
