I found myself playing around trying to work out the values of my Accelerometer, so I made this simple app. It will display the X / Y direction values and visually relay it as a bubble in the middle of the screen.

I'd be interested to know what people get as a max value. Tipping my phone gets 1.0. Shaking it takes it to 1.5 and beyond

Neat app BatVink! I can't test it on my mobile devices because I haven't got myself a Mac yet but this will be a very handy app when I can test on my mobile devices. Just using arrowkeys I get -1.0 to 1.0.

Minor update, adds Angle and Speed.

Angle on my Android is 0 degrees when tilting the phone forwards, 180 degrees backwards, and working in a clockwise direction.

Speed appears to be the vector of horizontal and vertical direction, always positive.
