Red Grid Link vs MeshWave

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.

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.
