• Find wall studs, screws, nails, pipes, and hidden metallic objects
• Real-time magnetic field readings in microtesla (µT)
• Live EMF meter and magnetometer graph visualization
• Signal confidence indicator for stronger detections
• Axis-based directional detection system
• Smooth real-time graphing of magnetic field activity
• Minimal, clean, and professional interface
• Fast and lightweight performance
• Works instantly with supported iPhones

HOW IT WORKS

The app uses your iPhone’s built-in magnetometer sensor to measure magnetic field strength. When metal or magnetic objects are nearby, the magnetic field changes and the app displays the variation in real time.

You can use Metal Detector to:

• Locate metal studs in walls
• Find hidden screws or nails
• Detect magnetic interference
• Measure EMF activity around electronics
• Explore magnets and magnetic fields
• Scan objects for metallic presence

GREAT FOR

• DIY & home improvement
• Construction & renovation
• Electricians & technicians
• Hobbyists & explorers
• Educational science experiments
• Everyday utility detection

IMPORTANT NOTES

• Accuracy depends on your iPhone’s magnetometer sensor
• Best results occur with ferromagnetic metals like iron and steel
• Does not work for non ferrous metal like Aluminum, gold, silver
• Thick walls or heavy interference can affect readings
• Remove magnetic phone accessories for improved accuracy
