## What is Metal Detector (Scanner)?

Metal Detector turns your iPhone into a smart magnetic field scanner for everyday checks, DIY projects, and quick on-site inspections.

Whether you are scanning walls before drilling, checking for hidden metal-related signal changes, or mapping detection points in a space, Metal Detector provides clear real-time tools for practical everyday use.

Using your device’s built-in magnetometer, the app measures nearby magnetic field changes in real time and presents them with a clear gauge, live graph, and directional cues so you can move toward stronger signals faster.

Key Features
• 3 scanning modes: Metal Detector, Stud Finder, and AR Scanner
• Real-time magnetic field visualization with instant signal strength feedback
• Detection presets for different use cases (general metal, wall studs, metal studs, pipes/plumbing, and electrical wiring)
• AR marker placement to map and revisit detection points in 3D space (supported devices)
• Smart calibration and sensitivity controls for different environments
• Sound and haptic feedback for hands-free scanning
• Support for µT and mG units

Built for Practical Use
• Locate hidden metal-like magnetic disturbances behind walls
• Assist with wall scanning before drilling or mounting
• Track signal peaks and compare scans over time
• Save sessions and review details later

Important Notes
• Results depend on your iPhone model, surrounding interference, and scanning technique.
• This app detects magnetic field variations and should be used as an aid, not as a substitute for professional detection equipment.
• AR Scanner requires AR-capable hardware.
