Red Grid Tactical

An offline-first tactical navigation mobile app that provides DAGR-class 10-digit MGRS coordinates, offline maps, and tactical tools for navigation where cell service is unavailable, with encrypted peer-to-peer team awareness over a radio mesh. It is for search and rescue teams, hunting parties, backcountry hiking groups, and training units that need to coordinate positions and waypoints without cell towers or servers. It is positioned as a $2,500 military-grade land-nav capability delivered on a phone with no accounts, no cloud sync, and on-device AES-256-GCM encryption, built with active-duty and retired U.S. Army soldiers.
