MGRS Vector is a precision land navigation toolkit built for military personnel, SAR teams, hikers, outdoorsmen, and serious navigators who require accurate, offline-capable tools in the field.

No ads. No data collection. No network required. Your privacy, respected.

30 day free trial.

Three powerful navigation tools in one app suite.

━━━━━━━━━━━━ 1) MGRS Vector

Calculate accurate MGRS / USNG polar vectors (distance + azimuth) from two coordinates — instantly and offline.

Whether you’re plotting a mission, navigating cross-country, or training in land navigation which may include improvised maps, MGRS Vector replaces manual protractor math with precise calculations.

Key Features:
• Works completely offline — no internet required
• On-demand GPS use (no constant battery drain)
• Will use network location if GPS is not available
• Detects and displays location accuracy
• Warns of inaccurate fixes (≥ ±20m)
• Supports 2-, 4-, 6-, 8-, and 10-digit coordinate precision
• Calculates: - Distance (meters) - Magnetic azimuth - Grid azimuth - True azimuth - Back azimuths
• Retrieves current local magnetic declination
• Converts metric distance to pace count and back
• Clipboard copy & share support
• Works as a pure mathematical (Cartesian) vector calculator
• Uses WGS84, the standard reference system and datum for the U.S. Department of Defense.
• Designed for field reliability and low power consumption.
• Verified with National Geodetic Survey calculator.


━━━━━━━━━━━━ 2) Pace Count Conversion

Purpose-built pace count calculator for field navigation.

Stop doing mental math under stress.

Features:
• Up to four named pace count profiles (e.g., LBE, Night, 72-hour pack)
• Convert meters → paces
• Convert paces → meters
• Automatically inject profiles into MGRS Vector • Instant PM factor calculation

━━━━━━━━━━━━ 3) Cartesian Coordinate Converter

Convert latitude/longitude coordinates into MGRS or USNG format.

Perfect when receiving coordinates from:
• GPS devices
• Map applications
• Web sources
• SAR or field reports

Features:
• Supports +/– or N/S E/W notation
• Supports Decimal Degrees (DD), Degrees Minutes Seconds (DMS), and Degrees Minutes (DMM)
• Auto-detects clipboard coordinate formats
• One-tap fix injection into MGRS Vector


━━━━━━━━━━━━ Privacy & Performance

• No ads — ever
• No tracking
• No "phoning home"
• No unnecessary permissions
• No network required for core functionality
• Extremely lightweight and battery-conscious
• Uses device GPS only when requested
• Android versions supported 8.1/9.0 to 16 and beyond
• Supported devices from small to large phones, foldables, tablets
• Quick Start guide
