This is a simple needle based compass, with fixed dial. It supports Azimuth as well as Quadrant bearing. Whats different? - I didn't find a compass app that can show Quadrant bearing - No ads Compass Details: - Only portrait mode - Point your phone(top part), to know the azimuth or quadrant reading. - Tap to switch between azimuth & quadrant mode. I have tested it on Wildfire & Nexus 7. Need testing on different devices. Any enhancement requests are more than welcome. If you like, you can leave a comment at playstore.
