Turn your iPhone into a powerful metal detector, EMF scanner and stud finder — all in one.

Detecto reads your device's magnetometer to measure the magnetic field around you in real time, with a live gauge, sound and vibration that react as you close in on a target.

DETECT METAL • Find ferrous metal: nails, pipes, rebar, screws and more • Live µT readout on a clear, easy-to-read gauge • Audio and haptic feedback that intensifies near metal

EMF SCANNER • Track electromagnetic fluctuation in real time • Spot wiring, outlets and electronic sources

STUD FINDER • Locate beams and studs behind walls • Edge-finding sweep so you drill in the right spot

BUILT FOR ACCURACY • One-tap calibration zeroes the baseline for clean readings • Adjustable sensitivity for indoor and outdoor use • Detection history — save spots and export to CSV

Whether you're hunting coins at the beach, finding a stud before hanging a shelf, or checking EMF around the house, Detecto gives you a fast, clear and reliable reading.

Note: Detecto uses your iPhone's built-in magnetometer. It detects ferrous (magnetic) metals and cannot reliably detect non-ferrous metals such as gold or silver. Readings are approximate.

Detecto Pro unlocks EMF and Stud modes, detection history, CSV export and full sensitivity tuning. Subscriptions auto-renew until cancelled.
