Read your grid. Build your field plan. 10digit brings MGRS navigation, offline maps, overlays and terrain planning into a clear field interface on iPhone and iPad. READ YOUR COORDINATES Use MGRS, UTM, or latitude and longitude alongside heading, altitude, speed, and reported horizontal accuracy. Coordinate precision and GPS accuracy are different; check the accuracy reading when using a position. PREPARE OFFLINE MAPS Download supported map regions before heading out. Keep saved maps, waypoints, and recorded tracks together when cell coverage is unavailable. Offline map use requires completing the relevant download in advance. BUILD AND SHARE YOUR PLAN Save waypoints, organize them into overlays, navigate by bearing and distance, and record your route. Import supported files and share locations with others. Pro adds live Team Overlays and KML, GeoJSON and encrypted layer exports. EXPLORE THE TERRAIN Pro terrain line of sight compares two points and shows visible and masked sections on an elevation profile. Snap to saved waypoints and share profile graphics. Terrain estimates are planning aids; they do not account for every building, tree or field condition. CONFIGURE YOUR TAK CONNECTION Pro includes experimental Cursor-on-Target networking and TAK Server connection settings, with server-package import. Choose when to connect and whether to broadcast your position. Deploy a temporary, private, cloud-hosted TAK server for exercises on demand. USE IT IN THE FIELD A large coordinate readout and a red-on-black night mode keep the interface easy to read in different conditions. CHOOSE WHAT YOU SHARE Navigation does not require a personal sign-up. Online maps request map tiles. Optional Team Overlay and TAK features send data when you choose to use them. Usage analytics are optional and can be controlled in Settings. OPTIONAL ONE-TIME PRO UPGRADE Start with core navigation and up to three offline map regions. Pro removes the region limit and adds the advanced sharing, terrain and planning tools shown in the app. Pro is a one-time purchase, with no subscription. Map availability and downloaded coverage depend on the selected source. GPS reception, battery life, and the accuracy reported by your device affect field use.
