GeoCalc is a free Android app developed by bitwize10 that calculates geographical coordinates given a start point, distance, and heading. It can also calculate the distance and heading between two points. The app is perfect for roadbook off-road racing, hiking, sailing, orienteering, geocaching, questing, treasure hunting, hobby flying, education, or anyone needing to calculate bearings and distances between coordinates.

The app uses an accurate ellipsoidal model of the Earth's surface for all calculations, ensuring precise results. GeoCalc also allows users to show points on the map, use coordinates from the current GPS position, and save all calculated points for future reference. Users can also share saved points with others. The app supports coordinates as decimals or DMS and metric, imperial, or nautical units.
