Compass - North, South, East, West Compass, Altimeter

Compass is a simple compass and altimeter app that uses your device's sensors to display the north, south, east, west, and current altitude.
It's lightweight and fast, with only the essential features, including magnetic north/true north switching, altitude, and coordinate display.

Key Features
● Displays north, south, east, and west directions
● Switches between magnetic and true north
● Displays current altitude (m) (based on barometric pressure sensor or GPS)
● Displays sensor accuracy and automatic calibration instructions

Permission Information
● Location permission: Used for altitude and coordinate calculations, and map linking functions
● Sensors (magnetometer, barometer): Used for direction and altitude measurement

Usage Tips
● The direction may fluctuate near metal objects or speakers.
● To improve accuracy, slowly move the device in a figure-of-eight (∞) pattern to calibrate the sensor.
● Uses Korean standard units (m, DMS) and does not support background operation.
