Compass is a sample android application which implements trivial compass functionality. It was created just as a code snippet reuse in some of my projects.
The main feature of the compass is noise filter (Low-pass filter) which make the arrow more stable in comparison to other similar applications where arrow always trembles.
You can install it from google play: https://play.google.com/store/apps/details?id=com.sevencrayons.compass
