MetalSense: Metal Finder

Uncover the unseen with MetalSense – your personal magnetic companion.

Ever lost your keys in the grass or wondered where that stud is hidden behind the drywall? MetalSense turns your smartphone into a powerful, portable metal detector using your device's built-in magnetometer.

Why choose MetalSense?
Precision Detection: Track magnetic field intensity in real-time. The app alerts you with clear audio signals and haptic feedback as you get closer to metal objects.
DIY & Safety Tool: Plan your home projects with confidence. Locate electrical wires, metal pipes, and wall studs before you drill.
Sleek, Intuitive UI: Features a high-contrast graph and a digital meter showing magnetic field levels in microteslas ($\mu T$) for instant, easy-to-read results.
Treasure Hunting Mode: Turn a walk on the beach or in the backyard into a fun exploration game for the whole family.

How it works:

Most smartphones are equipped with a magnetic sensor used for compass navigation. MetalSense taps into this hardware, translating the raw data into a visual and audible scanning tool that reacts to iron, steel, and other ferromagnetic materials.

Pro Tip: Because this app relies on your phone's magnetic sensor, it is designed to detect ferromagnetic metals. Please note that non-ferrous metals like gold, silver, or aluminum generally do not trigger magnetic sensors.
