PlotZone: MGRS & UTM plotter

Your position, followed live. The GPS button used to take a single fix, which went stale the moment you walked. It now follows you, with its accuracy shown. Where to go. Tap a point of the mission, or any spot on the map, while your position is followed: bearing and distance from where you stand, updated at every step, with a line drawn to it. The last thing you tap is the target. True or magnetic. Bearings now read in either north, your choice in the settings. The declination is the one where you stand, reported by the device itself, so nothing is downloaded and nothing is modelled. The MGRS grid, at last. The app is named for MGRS and UTM and could not draw their grid. It draws it now, at 1 km or 100 m, labelled like a military map: grid zone, 100 km square and the principal digits of every line. At a grid zone junction the grid switches zones with you, so the digits you read always match your position. Four new export formats. A plain-text brief you can paste straight into a message, with bearings and distances. CSV for a spreadsheet. GeoJSON for QGIS and mapping tools. OpenAir for flight computers, where a zone becomes a polygon and a point with a radius becomes a circle. The Bull's Eye now belongs to the mission. It survives closing the app, each mission keeps its own, and it travels inside the exported file, so whoever receives the mission reads the same bearings you do. Duplicate a mission from its menu, points, zones and all, to build a variant without typing it again. The point-plotting map offers the same three base maps as the map tab, and remembers the choice across both. Tap a point and its label stays open until you tap elsewhere. It used to close on its own after half a second. Larger text. Everything follows the iOS accessibility setting, except the round map buttons, which carry a symbol rather than text. Your own maps, offline. Import an MBTiles file: its tiles are copied to the device and drawn over Apple's map, so your sector stays readable with no network at all. A long press on its name deletes it along with its tiles. Five geodetic datums. WGS84, NAD27, ED50, OSGB36 and AGD66. Every coordinate is read and typed in the one you pick, for the chart you actually hold. Files open straight from Mail. A mission, an airspace file or an offline map received by message or AirDrop now opens in PlotZone, without hunting for it in the file picker. A KML can be either a mission or an airspace: the app asks rather than guesses. A point from a bearing and a distance. From any point of the mission, give a bearing and a distance, and the new point is plotted. The way a position is passed on the radio. The declination by hand. The app finds it on its own, but you can now type it yourself in the settings: 2 for 2° east, -5 for 5° west. Metal nearby deflects any compass, and your own value beats a deflected one. A bearing is then given magnetic. Measure between two plotted points. The measure tool only saw taps on the map, because a marker keeps the touch: tapping a plotted point now feeds it too. Reading back what it writes. Degrees decimals shown as 45.866477°N are now accepted as typed input, which they were not. A radius in nautical miles prints NM, not nm. And the brief says that its bearings are true, since it is read elsewhere. Wording. The Bull's Eye gives a bearing, not a heading, and the settings note now says so in every language that had it wrong. The base map labels were showing in French to everyone; they are translated.
