Compass Free is a navigation application that adds a compass to your Android device. The app uses either a built-in magnetic compass or a sun compass to determine the north direction. This makes it a useful tool for all outdoor activities, including hiking, biking, and camping. One of the best features of this app is that the sun compass is not affected by magnetic anomalies, making it a reliable tool for navigation.

The application is free to use, but it is ad-supported. This means that you may see ads while using the app. However, the ads are not intrusive and do not affect the functionality of the app. With its simple user interface, Compass Free is easy to use and provides accurate navigation information.
