About

Metal Detector EMF

This application uses your smartphone's magnetic sensor to detect nearby metal objects. It can help you find hidden metallic items, act as a treasure hunting tool, or even assist in ghost hunting by visualizing magnetic field trends. Requires a device with a magnetic sensor to function.

Highlights
  • Detects nearby metal
  • Measures magnetic field
  • Finds hidden metallic objects
  • Acts as a treasure hunter tool
  • Assists ghost hunters
  • Visualizes reading trends with a graph

Metal Detector EMF detects the presence of metal nearby. Metal detectors measure magnetic field value using a magnetic sensor that is built into your smartphone. Now You can easily find metallic objects that are hidden underground, behind walls etc. , or be a treasure hunter or ghost hunters, also see a reading trend through the graph. Simple app in your device called Gauss Meter are used for measuring the Earth's magnetic field but can't detect silver, gold, copper coins (non-ferrous - no magnetic field). This Magnetometer app require a magnetic sensor otherwise does not work.

Check out the areas where you work (desk, meeting rooms), where you sleep (bed), where you relax (couch, living room) and find the levels of EMF you are exposed to. Also use the app to measure the fields emitted by your appliances (computer, fridge, speaker, phone...). PROFESSIONAL MAGNETIC FIELD ANALYZER & GAUSS METER: Discover the invisible magnetic world around you. Using your device’s internal magnetometer, the app provides a comprehensive look at the electromagnetic fields (ELF) generated by electronic devices, wiring, and ferromagnetic materials. NEW PROFESSIONAL FEATURES: - 3-Axis Vector Analysis: Real-time $x, y,$ and $z$ coordinate tracking for precise field directionality. - Interactive History Graphs: Visualize time evolution with high-resolution charts that track spikes and trends. - Clean Signal Mode (LPF): Toggle an advanced Low-Pass Filter to stabilize readings and remove sensor jitter for professional-grade clarity - Save & Export Logs: Record your sessions and export data for further analysis in external software. VERSATILE USE CASES: Electronics Inspection: Measure the magnetic footprint of computers, speakers, and home appliances. Metal Detection: Locate ferromagnetic objects like iron pipes or steel studs behind walls. Interference Calibration: Find the "quietest" zones for sensitive electronic equipment or audio setups. USER EXPECTATIONS & DISCLOSURE: This app is designed as a sophisticated utility for detecting Magnetic Fields (ELF). What it detects: Magnetic flux from magnets, ferrous metals, and the low-frequency electromagnetic fields emitted by electronic components, power supplies, and speakers. What it does NOT detect: This app is not a radio frequency (RF) scanner. It cannot detect Wi-Fi signals, Bluetooth, 5G cellular radiation, or microwave leakage.
