This is simple app with a serious side. It can be mesmerising to watch if your are travelling by train or bus and it shows just how sensitive the accelerometer device is. If you are checking for vibrations this can be very useful, detecting the smallest movement. In developing the graph used by this application we used the accelerometers to supply data and found the results useful and entertaining so we thought we would let everyone play with it. And here is the result ! The app supports a delta mode plus a raw mode and has two help pages, one for delta mode and one for raw mode. It can be configured for thick or thin traces and each axis can be enabled or disabled. The graph supports to modes, pen chart mode and a more traditional oscilloscope mode. You can also Print or Email an image of the trace, and even email the data itself, in an xml format (annotated xml file format available on request ). The application has a trace viewer page where you can examine the trace in detail, switching on and off individual axis traces by accessing a menu using a swipe up gesture plus zooming in and out or scrolling through the trace. Traces can be saved from the main screen by accessing additional menu options using a swipe up gesture. The traces are tagged with the time and location when they were saved. All the information is contained in the data file in xml format. Gain and sample rate is also included. Have fun and if you want more features please let us know.
