MGRS GPS: Grid & Land Nav

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

MAKE IT YOURS
• Choose the typeface and color of the grid readout and every data tile
• Six style packs, from instrument green to a true 14-segment amber LCD
• Style one tile on its own, or hand the whole screen to the readout

ONE-TAP SHARING
• Tap any readout to copy your grid instantly
• Share via the system share sheet
• Send a waypoint as a QR code

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
• Measure ruler reads distance in degrees AND mils
• 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

TRACK RECORDING

• Export tracks as GPX

IMPORT & EXPORT

• KML and CSV import / export

APPLE WATCH
• Glance at your grid and bearing on your wrist

PRIVATE BY DESIGN
