Metal Detector & Magnet Finder

Explore magnetic fields and look for nearby iron, steel and magnets with your phone's built-in magnetic sensor. Follow the changing signal, mark what you find and keep a record of your search.

LIVE DETECTOR
• See field strength in microtesla or gauss, with separate Baseline, Change and Peak readings.
• Follow changes on the live waveform and signal lights.
• Choose Big number or Color field, adjust sensitivity, and use sound or vibration feedback.
• Re-zero when you need a fresh reference, or undo it to restore the opening baseline.

SAVE FINDS AND SEARCHES
Mark a find with a name, type, note, photo and optional location. Review your finds on a map, walk back to a saved spot, or use Lost item outdoors to keep a search trail coloured by magnetic change. Export finds and trails as GPX, KML or CSV.

KEEP A SCAN LOG
Start a log to record field strength and changes over time. Add audio, capture video with the reading on it, and keep marked finds with the log. Revisit charts, readings and media, then save or share a PDF report, CSV readings or the recorded audio.

EXPLORE THE FIELD
Open Field vector to see X, Y and Z readings, the field's direction through your phone and its dip angle. Hold a reading, compare places or record field-vector measurements as CSV.

KNOW YOUR SENSOR
Check an item's magnetic response, identify a magnet's north or south pole, locate your phone's sensor and view its specifications. Built-in Help explains the tools and what the sensor can find.

Explore all features ad-free during the five-day introductory trial. Basic measurement remains available afterwards; advanced features have access limits.

A magnetic sensor is required. Detection works at short distances and depends on the phone, object and nearby interference. Gold, silver, copper and aluminium are not directly detected. Readings cannot identify an exact metal type or confirm authenticity.
