MGRS GPS: Grid & Land Nav

Reworked overlays — group, browse, and frame waypoint sets on the map. Plus landscape layouts, a live crosshair HUD, and smoother Dynamic Island and widgets.

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, organise them into colour-coded overlays, navigate with a clear bearing-and-distance display, record breadcrumb tracks, and keep working when the cell signal drops.
