What it does

Your position, five ways — MGRS/USNG/UTM/Lat-Long/OSNG at a glance, in large high-contrast type, with WGS 84, NAD 27, OSGB 36, AGD 66 and ED 50 datums.
Compass navigation — arrow, bearing, distance and a terrain-aware ETA to the active waypoint.
Map with an MGRS grid overlay — a crosshair to drop a waypoint on a point you can see, and a ruler that snaps to your waypoints.
Waypoints — mark your position, type a coordinate in any format, or project by distance and bearing. Organize into overlays.
Route planning — multi-stop routes with cumulative distance and elevation.
Background track recording — a breadcrumb trail while the phone is locked, with map replay and an on-device summary of distance, climb, pace and terrain.
On-device intelligence — terrain-aware ETA, "optimize for terrain" route suggestions, voice waypoint capture, and recurring-hazard flagging. All offline.
Apple Watch — current coordinate, bearing/distance to destination, and a Mark Waypoint button.
English and Arabic, with full right-to-left layout.

Privacy in one line: your location, waypoints, routes and tracks stay on your device and are never uploaded. No account, no ads, no analytics, no trackers.
