Metal Detector & EMF Meter

Metal detector and stud finder for your phone: find iron and steel, locate the nails and screws in a wall before you drill, and scan a whole wall as a heat map. It uses the magnetic sensor already built into your phone, no extra hardware.

Honest up front: a phone's magnetometer only feels ferrous metal (iron, steel, nails, screws, rebar, steel pipes) a few centimeters away. It does not find gold, silver, copper or aluminum, and it is not an X-ray.

WALL SCAN WITH HEAT MAP
• With AR: aim at the corners of the area and press plus, any shape, the size is measured for you
• Without AR: take a photo or start without one, draw the shape and type the size
• Lay the phone on the wall point by point, the heat map then shows where screws, nails and steel pipes sit
• Share the result as a picture

STUD FINDER FOR WALLS
• Wall mode finds the screws and nails that hold drywall to the studs
• A track and a tone tell you when you are right over a fastener
• Mark the spot, then look for the next one

METAL DETECTOR
• Zeroes itself at the start, then you sweep slowly over the spot
• The ring and the live curve show the strength, with sound and vibration
• Set the alarm level and sensitivity, keep the peak, freeze the reading
• Units µT, mG or G
• EMF meter for the magnetic field of magnets, motors and live cables, not for Wi-Fi or 5G

RECORDING WITH GPS MAP
• Record the readings while you walk, every find lands on the map
• Download offline maps for the field, recording goes on with the screen off
• Share as a picture, a video or a 3D flight over your route, export GPX and CSV

WHY THIS METAL DETECTOR
• Works offline in more than 70 languages
• No account, no sign-up
• A small banner, and now and then a full-screen ad after a finished measurement

Use it to narrow down the search and check again before you drill.
