This App uses the World Magnetic Model developed by NOAA to determine the magnetic declination very accurately at any latitude, longitude and elevation of your choice, anywhere on the planet. This App was originally introduced using objective-C tools and has now been upgraded with new features to Swift and SwiftUI tools. There is a full built-in description in the App.
MagVar
This navigation tool calculates magnetic variation, the difference between true and magnetic north, essential for plotting courses on maps. It's designed for pilots, sailors, cartographers, and anyone using maps and a compass.
- Magnetic variation calculation
- True vs. magnetic north difference
- Map overlay display
- Accurate for 2025-2029
- Declination and inclination calculation

MagVar is targeted towards anyone interested in navigation. This includes, pilots of aircraft, captains of sea going vessels, cartographers, engineers and surveyors. Anyone who uses maps and a compass will find the declination calculation (also referred to magnetic variation) very useful. (Declination is the difference between true and magnetic north and used when plotting a course on a map.) MagVar calculates the magnetic flux density for any location on the Earth and then uses this data to calculate magnetic variation. The model is accurate for dates ranging from January 1, 2025 up through December 31, 2029. Using the model, the app calculates declination and inclination. As the user pans the map, the magnetic variation is calculated and graphically shown as a map overlay.
