I have found an awesome mobile App for detecting metals, It will work with magnetic field sensor so if your devices does not have one than this app is useless. But if your device has a magnetic field than tha app works and this app available for both iOS/Android devices.
It allows you to identify metal objects and its measurement, check the Video
