Start a route, explore the globe, and share the finished map. This English guide follows the current controls on iPhone, iPhone Duo, iPad, and Mac.
Route and Appearance are the two starting points on the globe. Their positions follow the screen, so the tools stay within reach as you turn an iPad or fold iPhone Duo.
The globe has no fixed axis, so a drag goes wherever you point it, including straight over the poles. That is the whole reason this app exists.
The search covers the full OurAirports database, so every strip with a code is in there.
Every waypoint shows its current conditions, temperature, and wind, courtesy of Open-Meteo.
Routes are not limited to airports. Any point on Earth can be a waypoint.
Every leg is measured and labeled, and the total rides at the top of the screen.
Routes save themselves as you build them, so a long multi-stop route never has to be typed twice.
A globe is for exploring, and a flat map is for sharing. Create Map gives you the flat map.
Appearance opens a native menu for how the world looks. Surface, Projection, and Units show their current choices.
Opens airport search and the waypoint list on the globe. On a wide iPad or Duo inner display, the route occupies a column beside the globe.
The red needle always points north. Tap it for north-up, drag its ring to roll the view by hand, and double-tap it to reset the camera entirely.
Centers and scales the globe to show the current route. It sits below the compass on iPhone, iPhone Duo, iPad, and Mac.
Steps the camera closer. Scrolling or pinching does the same thing, aimed at your cursor or fingers.
Steps the camera back, out to a full view of the globe.
Opens Surface, Projection, and Units, followed by the Borders, Cities, Airports, and Grid switches. Create Map is a separate action.
Renders the current route as a flat map image, with sliders for the size of its points and labels, and opens it with Share and Save buttons.
The running distance of the whole route in your chosen units. Create Map opens the export preview, and Clear removes the current waypoints.
Open Settings for map defaults and viewing preferences. Every change applies to the globe immediately and is remembered for next time.
Dark and Light are vector maps drawn from Natural Earth data, with roads and city names that appear as you zoom in. Satellite is NASA Blue Marble imagery, and Relief is the Natural Earth terrain map. The globe switches instantly.
Normal is a regular perspective camera. Ortho removes the perspective entirely and draws the globe the way charts do.
Kilometers, nautical miles, or statute miles, applied to every leg label, total, and history entry at once.
The Natural Earth country boundary lines drawn over the surface.
The major-airport markers around the globe. Tap one to add it to the route, or double-click it on Mac.
The city names on the Dark and Light maps as you zoom in.
A latitude and longitude graticule over the globe.
The distance labels that ride along each leg of the route.
Whether the images Create Map produces carry the leg labels too.
The current conditions line under each waypoint in the route panel, and the app's only network request.
A gentle rotation whenever you leave the globe alone.
Automatic saving of every route you build. Turn it off and History keeps only what it already has.
The thickness of the route arcs, from hairline to bold.
The size of every label on the globe.
