Every other mapping app pins the globe to the Earth's axis and treats the poles as the edge of the world. Airplanes don't. Great Circle Map rotates freely in every direction, so you can follow a polar route exactly the way it is flown.
Two airport codes and the route appears, measured leg by leg. Double-tap anywhere for waypoints of your own, as many as the route needs.
Google Maps and the rest fix the globe around the Earth's axis, so a polar route always slides sideways off the top of the screen. Great Circle Map has no fixed axis. Drag straight over either pole and keep going.
Type an IATA code, an ICAO code, or a city name. Every strip with a code is in there, and two airports are all it takes to see the great circle and its distance.
Distance labels ride along each leg with its initial bearing, and the running total stays pinned at the top. Units switch between km, nm, and mi anytime.
The map is tappable. Double-tap any point on the globe to create a waypoint there, and double-tap the waypoint again to delete it. There is no limit on how many you add.
A globe is for exploring, and a flat map is for sharing. Create Map unrolls the route into a clean flat image, polar legs and all, ready to send or save.
Each waypoint shows current conditions, temperature, and wind in knots, so you know what the air is doing along the whole route.
History saves your recent routes automatically and recreates any of them with one tap, which you will appreciate after entering a route with a dozen waypoints.
No analytics, no account, and no ads. Your routes stay on your device, and the only network request the app makes is for the weather.
NASA Blue Marble satellite imagery for the real view from above, or the Natural Earth relief map when terrain is what matters. One tap in the layers menu switches between them, and the same menu flips the camera between the Normal and flat Ortho projections.
Great Circle Map is a real Mac app, not a website in a window. The globe fills a resizable window with the route panel alongside it, driven by the same engine as the phone, and one App Store purchase covers iPhone, iPad, and Mac.
The guide walks through every feature with a screenshot, from your first polar spin to sharing a finished route map.
On the App Store for iPhone, iPad, and Mac, and on Google Play for Android.
