Altitude Compass

1. Download and open the app, then allow Location and Motion permissions; if your device has a barometer, enable pressure access for higher accuracy. 2. Calibrate once: move your phone in a figure-eight for the compass, set a known elevation or local sea-level pressure, and choose feet or meters plus true or magnetic north. 3. View the dashboard to see current heading, altitude, and pressure; tap to lock a bearing or set a waypoint from your location or coordinates. 4. Navigate by rotating until the direction arrow aligns with your target and monitor elevation gain as you move; basic readings work offline. 5. Optional: save favorite spots and logs for later, enable barometer smoothing for stable readings, and customize display fields to fit your trip.
