Signal Tracker: Wi-Fi & EMF

Signal Tracker is your all-in-one wireless signal scanner, electromagnetic field (EMF) radiation meter, and network security diagnostic suite.

Struggling with slow Wi-Fi? Wondering about electromagnetic radiation around your bed or desk? Or looking to ensure your privacy while traveling in hotels or rentals? Signal Tracker turns your smartphone's built-in hardware sensors into a professional diagnostic laboratory.

Switch seamlessly between Simple Mode for fast one-tap scans and Expert Mode for in-depth radio frequency (RF) metrics and network topology.

POWERFUL FEATURE MODULES
==================================

1. Wi-Fi & Network Analyzer
• Real-time dual-band scanning across 2.4 GHz and 5 GHz Wi-Fi frequencies.
• Precise signal strength monitoring (dBm / RSSI) with dynamic digital gauges.
• Wi-Fi Channel Analyzer: Detect channel congestion and identify the cleanest, least crowded channel for your wireless router.
• Local Network Device Scanner: Discover all connected phones, computers, and smart devices with IP, MAC address, and vendor identification.
• Network Topology Map: Visually explore the hierarchical structure and connected devices on your network.

2. EMF Radiation & Magnetic Field Detector
• Accurately measures electromagnetic field intensity in microteslas (µT) using your phone's built-in magnetometer.
• Geiger-counter style animated interface with real-time audio ticks and haptic vibration feedback.
• Configurable alert thresholds to notify you immediately when entering high electromagnetic radiation zones.

3. Bluetooth & Tracker Device Scanner
• Discover all nearby active Bluetooth (BLE) devices, beacons, and smart accessories with live proximity estimation.
• Trusted Devices List: Whitelist your personal electronics to isolate unfamiliar or suspicious signals instantly.
• Anti-stalking protection: Detect persistent nearby trackers and rogue tracking devices.

4. AR Optical Lens & Camera Finder
• Use your camera sensor with flashlight illumination to uncover glints and reflections from hidden lenses.
• Augmented Reality (AR) target crosshair assists in methodically inspecting suspicious hardware.

5. Acoustic Spectrum & Decibel Sound Meter
• Measure environmental noise levels accurately in real-time decibels (dB).
• Scan for high-frequency acoustic anomalies and ultrasonic interference patterns.

6. Wi-Fi Signal Heatmap & Waterfall Display
• Walk through your home or office to generate an interactive Wi-Fi coverage Heatmap and pinpoint dead zones.
• Live Signal Waterfall graph dynamically plots frequency stability and RF noise over time.

7. Security Audit Checklist & PDF Reports
• Step-by-step physical inspection checklist for hotel rooms, airbnbs, mirrors, power sockets, and smoke alarms.
• Export comprehensive security audits, peak EMF readings, and network inventories as formatted PDF reports.
• Built-in AI Assistant provides instant, tailored tips to resolve signal drops and improve network speed.
