LBalance is an app that uses the acceleration sensors of the device to move graphical objects on the screen. LBalance can also be used as a protractor or spirit level. Several graphical representations have been implemented. Beside own creations there are layouts inspired from the layout of known similar apps. The different layouts can be switched by the user. Also exists an overview display for direct selection. The calibration of the angle display follows the pattern of simple apps of this kind and applies to each main orientation of the device separately.
