🧲 REAL-TIME MAGNETIC DETECTION
━━━━━━━━━━━━━━━━━━━━━━━
DetecTerra uses your phone's built-in magnetometer to detect magnetic field variations. Lost keys, buried box, forgotten tool... the moment an object is detected, your phone vibrates and plays a sound alert.

Sonar mode emits a continuous beep whose frequency and volume increase as you approach an object. Perfect for scanning an area without looking at the screen, even with the screen off.

━━━━━━━━━━━━━━━━━━━━━━━
📍 GEOLOCATION AND MARKERS
━━━━━━━━━━━━━━━━━━━━━━━
Every detection is pinned on an interactive map at your exact GPS position. Place markers manually by tapping on the map or directly at your GPS position.

Choose from 5 marker colors, add a comment and photo to each point. Edit name, color and comment at any time. Measure the distance between two points directly on the map. Share a point's location via Google Maps or OpenStreetMap.
