GPS Tool Ultra-Coordinates

GPS Tool Ultra is an all-in-one GPS toolkit for anyone who works with coordinates — surveyors, engineers, hikers, geocachers, pilots, and outdoor professionals. Measure distance and area on an interactive map, convert coordinates across 5 professional formats, and run precise geodesic calculations — all in one app, with your data processed on your device.

ACCURATE GPS POSITIONING
• View your current coordinates in real time with latitude, longitude, and altitude
• Built-in barometer and magnetometer support: live atmospheric pressure (hPa) and magnetic field (µT) readings
• Search any address or place name, or jump straight to a coordinate pair
• Tap the map to drop markers and read exact positions

MEASURE ON THE MAP
• Distance: multi-point path measurement with live total length
• Area: polygon measurement with perimeter display at the same time
• Save, copy, and share any measurement result instantly

PROFESSIONAL CALCULATOR
• Distance between two or more points — choose Haversine for speed or Vincenty for highest geodesic precision
• Polygon area via spherical line integration
• Initial and final bearing (azimuth) between two points
• Geodesic midpoint between two coordinates

5-FORMAT COORDINATE CONVERTER
Convert instantly between:
• Decimal Degrees (DD)
• Degrees Minutes Seconds (DMS)
• Degrees Decimal Minutes (DMM)
• UTM (Universal Transverse Mercator)
• MGRS (Military Grid Reference System)
Plus built-in length units (m, km, mi, ft, nmi) and area units (m², ha, acre, km²) converters.

WORKS FOR YOU
