8月30日 的 MGRS GPS: Grid & Land Nav 應用程式分析

MGRS GPS turns your iPhone into a fast, glanceable military grid reference readout — built for soldiers, search-and-rescue teams, hunters, hikers, orienteers, and field researchers who think in grids and often work without a signal. Your position is shown as a large, high-contrast MGRS grid you can read at arm's length and copy with one tap. Mark waypoints, organize them into color-coded overlays, navigate with a clear bearing-and-distance display, record breadcrumb tracks, and keep working when the cell signal drops. POSITION, ANY FORMAT • MGRS / USNG military grid reference • UTM / UPS • Latitude / Longitude (decimal, DDM, DMS) • OSGB British National Grid • Show up to three formats at once • Each extra coordinate format can now be shown in its own datum • Coordinate engine validated against GeographicLib conventions ONE-TAP SHARING • Tap any readout to copy your grid instantly • Share via the system share sheet • Send a waypoint as a QR code • AirDrop waypoints between devices WAYPOINTS & OVERLAYS • Mark your current location, a map point, or type a grid • Group waypoints into toggleable, color-coded overlays • Draw lines and polygons for routes, sectors, and boundaries • Plan multi-point routes with per-leg distance and bearing • Projected waypoints — create a point from a range and bearing off any origin • Military symbols for friendly, hostile, neutral, and unknown units MAP WITH A REAL GRID • Smooth, labeled MGRS / UTM grid overlay • Waypoint markers and gentle clustering • Measure ruler reads distance in degrees AND mils • Follow mode keeps your current zoom • Range rings around your position, the map centre, or any waypoint • Area shapes — place a square, rectangle, or circle from a centre point and a size • Night vision — the whole app turns red, map included, with a one-tap switch on the Map screen NAVIGATE • Big bearing arrow, distance, cross-track, and ETA • True, magnetic, or grid north reference • Offline magnetic declination from an embedded World Magnetic Model (WMM2025) • Arrival alert with haptic feedback WORKS OFFLINE • Built-in USGS topographic, imagery, and shaded-relief basemaps • Download map areas for offline use — frame a box, pick the detail level, and see the tile count and size before it starts • Offline Maps manager: rename, delete, and see what each area costs on disk • Import your own offline maps (MBTiles raster) • Add your own tile server for coverage outside the US • Core navigation works with no cell signal • Offline indicator so you always know your status TRACK RECORDING • Record breadcrumb tracks with distance, elevation gain, and time • Export tracks as GPX IMPORT & EXPORT • Full GPX import / export (waypoints + tracks) • KML and CSV import / export • Open GPX files shared from other apps APPLE WATCH • Glance at your grid and bearing on your wrist PRIVATE BY DESIGN • No ads • No subscriptions • No accounts, no cloud sign-in • No analytics SDKs or third-party trackers • Your data stays on your device MGRS GPS is a one-time purchase — every feature is included. No subscriptions, no in-app purchases, and no ads, ever. Not certified for aviation, marine, surveying, live-fire, or military operations. Always carry a backup means of navigation.
