Measure point-to-point distances, or drop multiple pins to get the area of a closed polygon. “As the crow flies” distances across any terrain, on any map style.
Compare
Two synchronized Apple Maps side by side, panning and zooming in lockstep. See two places on earth at the same scale — compare city layouts, coastlines, neighborhoods, anything.
