About this app

Bearing Angle is a modern utility built to bring the time-tested precision of classical field surveying right into the palm of your hand. Inspired by the legacy of old-school surveyors tracking iron boundary pegs across rugged terrain, this application transforms your device's raw hardware sensors into a highly accurate, digital mathematical compass. Whether you are calculating boundary lines for a fencing layout, navigating historical maps, or tracking property lines, Bearing Angle replaces guesswork with absolute geometric certainty.

Key Capabilities
Degrees, Minutes, Seconds (DMS) Parsing: Features a rugged real-time validator that handles field data natively—just like standard land survey deeds.
True North Calibration: Built-in magnetic declination shifting allows you to input local variances (15.0° baseline or custom) to instantly map the difference between Magnetic North and True North.
Dynamic Geometric Arcs: The custom drawing layout maps two intersecting bearings concurrently, instantly computing the relative angular differences and scaled cross-distances.
Tilt & Pitch Compensation: Tracks the forward and backward tilt of your phone in real time, ensuring that even on steep slopes or uneven earth, you know exactly how level your perspective is.

Use Case.
Borders & Fencing:
Calculate exact angular cut-offs for property fencing, ensuring your posts align perfectly to deed coordinates.
Locating Surveyor Pegs:
Use real-time azimuth tracking alongside local declination variables to find hidden, historical boundary markers.
Map Navigation & Orienteering:
Cross-reference physical paper maps with real-world sightlines by plotting visual vectors over the static heading line.
