Fengshui Compass is a free Android app developed by DarkCompet that offers users a magnetic and GPS compass with Google Maps integration. The app allows users to customize the compass, search for a place via address or latitude and longitude, locate their location via GPS, and navigate with the magnetic compass. Users can also save and share their measured data, including place and compass information. The app supports material design with multiple app themes and is available in English, Japanese, and Vietnamese languages.

The paid version of the app offers additional features such as the ability to locate or calculate direction at any location that appears on Google Maps and the option to hide ads. However, it is important to note that to use the compass feature on Android, the device must have a magnetic sensor equipped to read the Earth's magnetic field. If the device does not have this feature, users can upgrade to the Pro version and measure with the compass on Google Maps. Additionally, users may need to manually calibrate the device with an 8-pattern if the magnetic sensor does not work well.

Overall, Fengshui Compass is a useful app for those in need of a magnetic and GPS compass on their Android device.
