Transform your smartphone into a smart, high-precision metal detector and EMF scanner with Metal Detector! Engineered with a sleek dark-mode glassmorphic interface, this essential utility tool uses your phone’s built-in 3-axis magnetometer sensor to accurately measure magnetic flux density in microteslas (µT).

Whether you are a DIY enthusiast looking for hidden iron pipes and screws in walls, locating lost metallic objects, or measuring electromagnetic fields (EMF) around electronics, Metal Detector gives you instant, dependable readings.

KEY FEATURES
• Real-Time Magnetic Field Detection (µT)
Directly tracks magnetic flux density through your device's built-in magnetic sensor. Watch instantaneous updates as you move closer to ferrous metals, hidden studs, and electrical conduits.
• Modern Radial Meter & Visual Alerts
A high-contrast neon radial gauge transitions dynamically from calm Cyan (normal ambient levels) to Warning Amber and High-Alert Red when strong magnetic anomalies are detected.
• Triple Alert System: Sound, Vibration, and Flash
Never miss an anomaly. Customize your notifications with quick toggles:
Acoustic Audio: Pitch and frequency scale upward as the magnetic reading spikes.
Haptic Feedback: Gentle vibrations pulse when crossing standard proximity thresholds.
Flash Alert: Optional flashlight strobe trigger for dark or low-visibility scanning environments.
• Multiple Visual Detection Modes
Switch seamlessly between different tracking displays to suit your project:
Radial Gauge: Intuitive central dial for fast sweeps and everyday checks.
Analog Dial: Classic speedometer-style needle view with colored sensitivity zones.
Digital Readout: Large, ultra-clear digital counter ideal for high-precision DIY tasks.
Live Graph Timeline: Continuous rolling chart showing wave fluctuations and spikes over time.
Camera Viewfinder HUD: Real-time on-screen sensor readout overlaid on your camera feed.

POPULAR USE CASES
• Home Improvement & DIY: Locate studs, iron nails, screws, and metal pipes concealed behind drywall before drilling.
• Find Lost Items: Scan grass, carpets, and sand for dropped keys, needles, coins, or iron fixtures.
• EMF & Radiation Exposure: Identify elevated electromagnetic radiation from household appliances, power lines, and transformers.
• Outdoor Exploration: A lightweight companion for treasure hunts, workshop scans, and hobby electronics.

HOW IT WORKS
The natural ambient magnetic field on Earth typically measures between 30 µT and 55 µT.
When you approach ferromagnetic objects (such as iron, steel, or nickel) or live electrical lines, the magnetic density reading spikes well above 70 µT.
The app instantly translates the raw 3-axis vectors into total magnitude and alerts you via sound, vibration, and bright visual rings!

HELPFUL TIPS FOR BEST RESULTS
• Sensor Calibration: If readings appear erratic or stuck, calibrate your phone by moving it smoothly in a "figure-8" motion in the air.
• Cases & Accessories: Thick phone cases, magnetic wallet clips, or metal kickstands can interfere with the internal magnetometer. Remove magnetic accessories for the most accurate sweeps.
• Metal Compatibility: The magnetometer detects ferromagnetic metals (iron, steel, cobalt, nickel). It does not detect non-magnetic materials such as gold, pure silver, copper, or aluminum.
