Quick Sensors lets you quickly get an overview of what kind of sensors your device supports. It will show them as tiles and the flip side of each tile will show you the values from each sensor. You can stop each tile from flipping by double tap on it, or you can freeze all tiles by brining up the App Bar. Currently the following sensors are detected: Geo Location, Accelerometer, Gyrometer, Compass, Inclinometer, Light sensor, Orientation & Simple orientation.
