Metal Detector EMF is a utility application designed for iPhone users, allowing them to detect nearby metallic objects using their device's built-in magnetic sensor. This app serves as a tool for treasure hunting or ghost hunting, enabling users to find metallic items that may be hidden underground or concealed behind walls. It features a graphical representation of the magnetic field readings, helping users visualize detection trends over time.

The application operates by measuring magnetic field values and requires a magnetic sensor to function effectively. It's important to note that while the app can detect various metals, it is unable to identify non-ferrous materials such as silver, gold, or copper coins, which do not generate a magnetic field. Overall, Metal Detector EMF offers a straightforward interface and practical functionality for anyone interested in exploring hidden treasures.
