12 Tactical Tools
Back azimuth, dead reckoning, two-point resection, pace count, declination, TDS, sun/moon, precision selector, elevation/slope, photo geostamp.
6 Report Templates
SALUTE, 9-Line MEDEVAC, SPOT report, ICS 201 briefing, CASEVAC request, CFF fire mission. Pre-formatted for radio transmission.
NATO Voice Readout
Proper phonetic pronunciation of grid coordinates. Shake to speak. Hands-free grid calls with correct NATO digit pronunciation.
External GPS
Garmin GLO, Bad Elf, and other BLE GPS receivers for enhanced accuracy beyond your phone's built-in GPS.
Mission Planning
Route overlay on map with leg distances and nearest-neighbor optimization. GPX/KML import via document picker, export via Share sheet.
Photo Geostamp
Burns MGRS coordinates and date-time-group onto photos. Tactical documentation without modifying camera roll originals.
4 Tactical Themes
Red Lens (night vision preservation), NVG Green (NOD compatible), Day White (high-contrast daylight), Blue Force (tactical blue). OLED true black.

Frequently Asked Questions
Is Red Grid MGRS free?
Yes. Free to download with full 10-digit MGRS, declination, core tools, and radio-ready reports. Pro unlocks all 12 tools, offline maps, mesh, every report and theme, and unlimited waypoints.
Does it work without an internet connection?
Yes. GPS talks directly to satellites: no cell tower, Wi-Fi, or internet required. Cache map tiles for your area and the map works fully offline.
What is MGRS, and how is it different from latitude/longitude?
MGRS is built on UTM with a grid-zone designator and 100 km square ID, giving shorter coordinates for radio voice reports and fast plotting. Need to convert one now? Try the free online MGRS converter.
Is this a replacement for the DAGR (AN/PSN-13)?
For training, STX lanes, ruck marches, and permissive GPS environments, yes, it runs the same core land-nav math. The DAGR's SAASM module matters in contested environments; for the other 90% of use, Red Grid covers it.
Does Red Grid MGRS collect or share my location?
No. Zero analytics, tracking, accounts, or crash reporting; your coordinates stay in device memory and never leave the phone. Verify it yourself: switch to airplane mode and the app keeps working.
Is Red Grid MGRS available on Android?
Yes. Live on Google Play with the same features, zero-network architecture, and pricing. Android 7+ (API 24+), phones and tablets.

All 12 tactical tools, offline maps, Meshtastic mesh, all 4 themes, unlimited waypoints, and all 6 radio-ready reports. Available at $3.99/month, $29.99/year, or $199.99 lifetime.
