âFrequently Asked Questions
How does the metal detector work?
The app uses your phone's built-in magnetometer (compass sensor) to detect changes in magnetic fields caused by ferrous metals.
What types of metal can it detect?
The app detects ferrous metals (iron, steel, etc.). Non-ferrous metals like gold, silver, and aluminum are harder to detect with magnetometers.
Can I find gold with this app?
Pure gold is non-ferrous and doesn't strongly affect magnetic fields. Gold jewelry with iron components may be detectable.
What's the detection range?
Detection range depends on metal size and type. Large ferrous objects may be detected from several inches away.
Why do I get readings without any metal?
Electronic devices, appliances, and building materials can affect magnetic fields. Calibrate in a neutral area for best results.
Is this as good as a real metal detector?
Professional metal detectors use different technology. This app is great for basic detection and fun, but not for serious treasure hunting.
How do I calibrate?
Move away from metal objects and electronic devices, then use the calibration feature in settings.
Does it work without internet?
Yes. The app uses only your phone's hardware sensor and works completely offline.
