Metal Detector & Magnet Finder

Look for nearby iron, many types of steel, and magnets with your phone’s magnetic sensor. Sweep slowly and follow changes on the Finder’s live graph, with adjustable sensitivity, sound and vibration. Set a baseline, track peaks, or inspect all three magnetic axes in Field vector.

Start a scan log and mark finds with notes, photos and optional locations. View finds and GPS search routes on a map, use Walk back to return to a saved find, or compare readings between spots. Check whether an item is magnetic and identify a magnet’s poles.

Save scan reports as PDFs with maps, or export finds and routes as GPX, KML or CSV. Use Tasks to make checklists with reminders and attachments.

A phone with a magnetic sensor is required. Detection range depends on the phone, the object and nearby interference. The sensor cannot directly detect gold, silver, copper or aluminum, and readings cannot identify the exact metal.
