Navigate with confidence using this simple, reliable, and fully offline Compass app. Instantly access true Geographic North, precise altitude above sea level, and detailed coordinate formats—perfect for hiking, travel, and outdoor survival navigation.

Designed for clarity and accuracy, the app uses trusted models like EGM96 and magnetic declination to deliver dependable readings anywhere. Whether you're exploring remote trails, planning route mapping for trekking, or checking sunrise and sunset times, this tool keeps you oriented at all times.

Built for adventure seekers and everyday users alike, it includes multiple dials, measurement tools, and high-contrast themes—optimized for hikers, campers, and anyone needing precise location data.

Key Features

• Works flawlessly offline with no network required • Accurate Geographic North via magnetic declination • True altitude above mean sea level (AMSL) using EGM96 • Sunrise & sunset times for outdoor planning • Azimuth angles in deg, grad, mrad, and gon • Multiple dials and color themes (including high-contrast) • Angle measurement with compatible dials • Bubble Level functionality (available in iPhone dial) • Coordinates in MGRS, UTM, DD, DMM, DMS • British National Grid (OSGB86) & SwissGrid (CH1903 / LV95 / MN95) • Magnetic field strength monitoring for detecting perturbations • Sensor accuracy display • Address lookup for your current location (requires data)

The compass performs best outdoors, away from magnetic interference. Note that magnetic closure cell phone cases may reduce accuracy.

EGM96 provides the geoid reference to calculate true altitude from GPS data, while UTM assigns precise coordinates across the Earth’s surface.

Have fun!
