G-Meter has now been confirmed working on two new phone models: Motorola Droid 4 and Sony Ericsson Xperia Ray, bringing the full list of confirmed tested phone models to:

HTC One V, One S, One X, Desire
Galaxy SII-III, Nexus
LG Optimus
Motorola Droid 4
Sony Ericsson Xperia Ray

If you downloaded this app and it works fine on your phone, I would greatly appreciate a quick email with your phone model, so I could update the list above. Thanks!

G-Meter is a free application available on Android Market that will use the phone's internal accelerometer to plot acceleration data on the graph and record max values.
