Physics Toolbox Compass 1.2 Apk

This compass app displays the cardinal directions (North, South, East, West), degrees, and bubble level. Use this app to determine direction of the earth's magnetic field, direction of magnets, or observe deflection as a result of an electromagnet. A bubble is displayed in the center of the compass, and the hairlines on the screen background and the bubble can be superimposed to ensure that the device is level.
