Avare is a free open source "moving map" aviation GPS, A/FD and EFB app for phones or tablets using the Android Operating System. The app uses an internal or external GPS to determine location, allowing real-time display of location, heading, speed, distance, and altitude on aviation and topographic charts. The user can also access all relevant FAA data and some non-FAA maps and data in flight without data connection, once it has been downloaded to the device. Ability to display ADS-B data, and to connect with an auto-pilot or flight simulator can be enabled with add-on free open source Avare apps.
