Store description excerpt

Your team. Your grid. No cell towers. No servers. No accounts. ATAK costs nothing but demands a TAK Server, Android-only deployment, and an IT team to run it. Red Grid Link delivers the core capabilities — encrypted team position sharing, MGRS-native navigation, offline maps, and tactical reports — on any iPhone, with zero infrastructure. Open the app. Start a session. Your team appears on the map. Built by an active duty Army officer for SAR teams, hunting parties, backcountry groups, and civilian units that need blue-force tracking without the bureaucracy. FIELD LINK — ENCRYPTED TEAM SYNC: Devices within Bluetooth range auto-discover each other and share encrypted positions, waypoints, and markers in real time. - AES-256-GCM encryption with ECDH P-256 ephemeral session keys - Live position updates every 5-30 seconds (battery-adaptive) - Cross-platform: iPhone and Android in the same session - Zero pairing, zero configuration, zero accounts - 2-device free tier, up to 8 devices with Pro+Link MGRS NAVIGATION: Live 10-digit Military Grid Reference System precision — the same coordinate system used by NATO forces worldwide. - 4/6/8/10-digit MGRS display (1-meter precision) - MGRS grid overlay at all zoom levels - Magnetic declination (WMM model) - NATO phonetic voice readout for hands-free grid calls OFFLINE MAPS: Download topographic regions over WiFi. Navigate completely offline. USGS Topo and OpenTopoMap coverage with MGRS grid rendering at every zoom level. EMERGENCY BEACON: One-tap SOS sends your GPS to every teammate. Full-screen alert with distance and bearing. Retransmits every 30 seconds until cancelled. TACTICAL MESSAGING: 8 pre-canned tactical messages plus free text. HELP, STOP, RALLY ON ME, ALL CLEAR, and more. One tap to send across the team. TEAM ROLES & COORDINATION: - Assign Lead, Scout, Medic, Comms, or custom roles with callsigns - Share waypoints with the team or keep them private - Draw boundaries and get alerted when anyone crosses them - Drop markers for hazards, rally points, objectives, or caches - Ghost markers show last-known positions when teammates go out of range 11 TACTICAL TOOLS: Dead Reckoning, Two-Point Resection, Pace Count, Back Azimuth, Coordinate Converter (MGRS / Lat-Lon / DMS / UTM / FixPhrase), Range Estimation, Slope Calculator, ETA / Speed, Magnetic Declination, Celestial Navigation, MGRS Precision Reference.

Terminology and quick actions adapt to your mission: Search & Rescue, Backcountry, Hunting, or Training.
