Rebuilt around your airports, plus a big new feature. RANGE RINGS Switch from the distance arrow to a range ring, type a radius, and tap anywhere on the chart to drop it there. ZOOM AND PAN Pinch, drag and double-tap to move around the chart. Zoom right in to put a point exactly on a threshold — the lines stay locked to the chart, and the handles stay the same size. MEASUREMENTS THAT STICK Lines are now anchored to the chart itself, so they survive zooming, rotating, and moving between iPhone and iPad. CALIBRATE TO ANYTHING Set the red line to any distance you know — a runway, a scale bar — instead of a fixed 1 km. Read results in meters, feet or nautical miles. AIRPORTS FIRST The app opens on your airport list: alphabetical, searchable, with a thumbnail of each chart. Add an airport by its ICAO code, then give it a chart. NOTHING TO SAVE Every change is written to that airport as you make it. ALSO - Bigger, easier-to-grab handles - Tap either label to change its setting - Rename airports; swipe left to delete - New How to Use guide behind the info button Upgrading from 1.0? Measurements now anchor to the chart rather than the screen, so lines on your existing airports will start at their default positions. Your charts and codes are safe — just set the calibration line once more.
