Metal Detector - EMF Scanner

Discover hidden metals around you with Metal Detector - EMF Scanner, the most powerful and beautifully designed metal detector app for Android. Turn your smartphone into a professional-grade metal and electromagnetic field (EMF) detector using your device's built-in magnetometer sensor.

Whether you're searching for lost keys, coins, nails, iron pipes behind walls, steel beams, electrical wiring, or hidden metallic objects — this app delivers real-time, accurate magnetic field measurements displayed on a stunning sci-fi inspired gauge interface.

★ KEY FEATURES

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

◉ REAL-TIME METAL DETECTION

Instantly detect ferromagnetic metals like iron, steel, nickel, and cobalt. The app measures magnetic field disturbances in microtesla (μT) and alerts you with visual, audio, and haptic feedback the moment metal is detected nearby.

◉ PROFESSIONAL GAUGE DISPLAY

A beautifully animated circular gauge shows the current magnetic field strength with color-coded zones — green for safe, yellow for weak detection, orange for medium, and red for strong metal presence. The smooth needle animation gives you precise, real-time readings.

◉ LIVE SIGNAL HISTORY GRAPH

Track magnetic field changes over time with a scrolling signal history graph. Perfect for scanning large areas and identifying exactly where metallic objects are hidden beneath surfaces.

◉ 3-AXIS MAGNETIC FIELD DATA

View detailed X, Y, and Z axis readings of the magnetic field. Understand the directional component of the magnetic field to pinpoint the exact location and orientation of metal objects.

◉ SOUND & VIBRATION ALERTS

Audio beeping increases in frequency as you get closer to metal — just like a professional metal detector. Haptic vibration feedback gets stronger with signal intensity. Both can be toggled on or off independently.

◉ ADJUSTABLE SENSITIVITY

Fine-tune the detection sensitivity from 5% to 100% using the built-in slider. Lower sensitivity for noisy environments, or crank it up for detecting small or deeply buried metallic objects.

◉ AUTO & MANUAL CALIBRATION

The app automatically calibrates to your environment's baseline magnetic field. You can also manually recalibrate at any time for more accurate readings in different locations.

★ HOW IT WORKS

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Your Android device contains a magnetometer sensor that measures the Earth's magnetic field. When a ferromagnetic metal object is nearby, it distorts the local magnetic field. Metal Detector measures these disturbances in real-time and converts them into easy-to-read gauge values, sound alerts, and vibration patterns.

Simply open the app, tap START SCANNING, and slowly move your phone near surfaces where you suspect metal might be hidden. The gauge needle will swing and the beeping will intensify as you approach metallic objects.

★ PERFECT FOR

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

• Home renovation and DIY projects

• Finding studs, pipes, and wiring in walls

• Treasure hunting and coin collecting

• Security screening and inspections

• Educational physics demonstrations

• Locating lost metal items

• Checking food for metal contaminants

• Construction and building inspection

Note: Detection accuracy depends on your device's magnetometer sensor. The app detects ferromagnetic metals (iron, steel, nickel) and may not detect non-magnetic metals like aluminum, copper, or gold.
