Magnetic Field Meter 앱 분석 (10월 1일)

Magnetic Field Meter turns your smartphone into a professional EMF detector, metal detector, RF signal analyzer, stud finder, ghost hunter, and digital compass — all in one app. It uses your device's built-in magnetometer to deliver accurate, real-time measurements with no extra hardware. ■ How Does It Detect Metal? Your phone's magnetometer measures the surrounding magnetic field in microtesla (μT). Ferrous metals — iron, steel, nickel, cobalt — distort the Earth's natural field (25–65 μT), and this app detects those distortions with vibration, sound, and color-coded visual feedback. Note: Non-ferrous metals (gold, silver, copper, aluminum) do not affect magnetic fields and require professional electromagnetic induction equipment to detect. ■ Adaptive AI Detection Engine Most EMF apps use a fixed threshold that causes false alarms. Magnetic Field Meter's Guarded EMA algorithm continuously learns your environment's magnetic baseline and adjusts automatically — accurate indoors, outdoors, and near electronics. The sensitivity slider (−30 to +30) lets you fine-tune from strict to highly sensitive. ■ Real-Time Measurement & Visualization - Live readings in μT, mG (milligauss), and A/m - Circular gauge with 13-level color gradient (green to red) - Scrolling line chart tracking up to 1,000 data points - Delta (Δ) display showing change from calibrated baseline - Min / Max / Threshold statistics updated continuously ■ Detection Alerts - Haptic vibration on magnetic anomaly detection - Audible alarm that scales with field intensity - Color-coded status indicator across the UI - Status bar notification with 7 one-tap shortcuts ■ RF Signal Meter Monitor Wi-Fi and cellular signal strength in real time. View connection details — SSID, RSSI, frequency, link speed for Wi-Fi; operator, signal dBm, network type for cellular. A dual-line live chart plots both signals. Scan nearby Wi-Fi networks with signal bars. ■ Stud Finder Find metal studs, pipes, and rebar behind walls using the magnetometer. A 3-step on-screen guide walks you through: hold your phone flat, tap Start, and slide slowly. Color-coded sensitivity feedback shows detection strength in real time. ■ Ghost Hunter Mode Fun paranormal EMF detector for parties with a matrix-style dark UI, 5-level activity bars, EVP log driven by real sensor data, and DTMF audio tones that intensify with EMF readings. For entertainment only. ■ EMF Recorder Log magnetic field data with timestamps and GPS coordinates. Browse history and export as CSV for analysis. ■ Digital Compass Aviation-style 360° heading display with N/S/E/W directions and smooth sensor-driven rotation. ■ Who Uses This App? - Home inspectors — locate iron pipes, rebar, steel studs in walls - DIY enthusiasts — find studs before drilling, detect buried metal - Electricians & engineers — measure EMF near power lines - Network technicians — diagnose Wi-Fi and cellular coverage - Students & educators — hands-on magnetism experiments - Ghost hunting fans — entertain friends with paranormal mode ■ What Can & Cannot Be Detected ✓ Iron, steel, nickel, cobalt, magnets, electromagnetic sources, Wi-Fi/cellular signals ✗ Gold, silver, copper, aluminum, brass, lead (non-magnetic) Dark & Light theme, 50+ languages, screen capture, baseline calibration, lightweight with no background drain.
