FlyOn Balloon Pilot

The FlyOn Pilot app is the next version balloon app developed from the HotAir app for Android. It includes target guidance, drawing lines and geometries, adding map overlays and supports a wide range of map formats including kml, aip, geojson, tile maps and more. UTM formats are supported in both 4/4 and 6/7 formats for competition use.
While the features may be super useful, the app is not a substitute for legally required flight planning and aviation instruments.
