FAQ
What coordinate formats does GEO Calc support?
GEO Calc supports Decimal Degrees, DDM, DMS, UTM, MGRS, USNG, and Plus Codes. The app can auto-detect the format and allows you to copy results with a single tap.
How accurate is the distance and bearing calculation?
GEO Calc uses Vincenty's algorithm for geodesic distance and forward azimuth calculations on the WGS84 ellipsoid, providing accurate results beyond simple flat-map approximations. The Pro version includes a direct geodesic calculator.
Can I use GEO Calc offline?
Map tiles load over the internet from OpenStreetMap. However, core calculation features and navigation to saved waypoints can function without an active internet connection once the necessary data is loaded.
What is the difference between the free and Pro versions?
The free version includes basic coordinate conversion, distance/bearing calculation, and up to 20 waypoints. GEO Calc Pro, a one-time purchase, unlocks the direct geodesic calculator, live GPS, field navigator, satellite map layer, GPX import, and unlimited waypoints.
