We track 207+ magnetic interference apps on the iOS App Store as of July 2026, ranked by rating, recency, and analysis of real user reviews.
This app uses your device's built-in magnetometer to detect and measure magnetic and electromagnetic fields. It can help you locate ferromagnetic metal objects like wires, pipes, coins, and keys, as well as discover hidden wood studs behind walls or plasterboard.
The app leverages your device's magnetic sensor to quantify the intensity of the magnetic field. When placed near ferromagnetic materials, these fields cause a disturbance, leading to an increase in the readings displayed by the app. An active detection beep alerts you when a certain limit is reached.
