Metal Detector is a free Android app developed by Refael Sheinker in the category of Utilities & Tools. This app utilizes the magnetic sensor built into your device to measure the magnetic field strength. With a simple and straightforward interface, Metal Detector allows users to detect the presence of metal in their surroundings.

To use the app, simply open it on your Android device and move it around metallic objects. If there is any metal in the area, the strength of the magnetic field should increase. However, it's important to note that the accuracy of the measurements depends on the sensor in your device. Additionally, the magnetic sensor can be affected by electronic equipment such as TVs and PCs due to electromagnetic waves.

While Metal Detector provides a convenient way to detect metal, it is important to keep in mind that it cannot detect gold, silver, or coins made of non-ferromagnetic metals like copper. Furthermore, the app may provide unwanted results if used near a leather case with a magnetic snap.
