Turn your smartphone into a functional metal finder and EMF meter!

Metal Detector: EMF Gauge uses your device’s built-in magnetic sensor (magnetometer) to measure magnetic field values (EMF) and pinpoint nearby ferrous metal objects easily.

Whether you are locating lost metal items, checking radiation levels around home appliances, or finding hidden pipes and studs behind drywall, this tool provides clear, real-time feedback.

KEY FEATURES:
• Accurate Metal Detection: Find ferrous metals like iron and steel effortlessly.
• Real-Time EMF Meter: Measure electromagnetic radiation in microtesla (µT).
• Dual Display: Analog gauge display and responsive digital graph meter.
• Sound & Vibration Alerts: Get instant audio and haptic feedback when levels spike.
• Sensitivity Control: Adjust detection threshold for different environments.
• Simple Calibration Guide: Quick sensor reset for maximum measurement reliability.

PRACTICAL USES:
1. Household Projects: Check for screws, electrical wires, and metal pipes inside walls before drilling.
2. EMF Measurement: Identify electromagnetic exposure around microwaves, laptops, and power lines.
3. Lost Object Finder: Scan grass, sand, or carpets for dropped keys, coins, or small iron tools.

HOW TO USE:
1. Open the app and keep it away from direct magnetic interference.
2. Move your device near the area you wish to scan.
3. Watch the digital gauge rise and listen for the sound alert as magnetic levels increase.
4. If readings seem unstable, recalibrate by waving your phone in a figure-8 pattern.

IMPORTANT NOTE & DISCLAIMER:
This app requires a built-in magnetic field sensor (magnetometer) to work. It detects ferromagnetic materials (iron, steel) and electromagnetic fields. It does not detect non-magnetic metals like pure gold, copper, or aluminum unless they are alloyed with magnetic materials or emit magnetic disruption.
