Metal Detector is a free application developed by BeshevGames for Android devices that allows users to detect the presence of metal nearby. This app uses the magnetic sensor (magnetometer) of your device to calculate the μT magnetic field around your device. The app features four light bulbs that light up as you get closer to the metal object. Moreover, a screen displays the μT (microtesla) value when a steel or iron metal object is near the device, and a graph represents the changes in the magnetic field when you move closer or further from the metal object.

Metal detectors are useful for finding hidden metals within objects, and this app can be a great tool for those who need to find metal inclusions. However, it is important to note that this app requires your device to have a magnetic sensor (magnetometer). Without this, the app will not work.

Using the app is very simple. Just open the metal detector and move your device to detect a metal object. The accuracy of the readings depends on your device's hardware, specifically its magnetometer. Overall, Metal Detector is a useful app that can help you find hidden metal objects and is definitely worth a try.
