The technologies we use today, from our everyday appliances, cell phones, even our cars, emit electromagnetic radiation & EM radiation that can penetrate and affect us, seriously compromising our health and disturbing our environments. When you come to magnetic radiation, the body is as easily penetrated as air. This means if you are near a powerful EMF, electromagnetic radiation isn’t just around you, it’s inside you. Your body’s electrical signals are well within the range of those that can be stimulated by ambient radio waves, microwaves and other forms of electromagnetic radiation. That harmful, unnatural type of stimulation can seriously impact your body. How can I find out what EMF levels I'm exposed to at home and at work? Now you can find out thanks to a new app for iPhone..EMF Radiation Detector! EMF Radiation Detector is very simple to use: open the app and your iPhone will begin to detect the electromagnetic fields nearby, showing you whether or not if these are dangerous to your health. Do not endanger in vain your health, download EMF Radiation Detector from the App Store and find out which electronic devices can be dangerous for your body. EMF Radiation Detector is compatible with iOS 7.1 or later. To ensure the accuracy of the data keep the iPhone away from metal objects, magnets and speakers.

> Detect Invisible Fields: Find the ElectroMagnetic Fields around you in seconds > Pro-Grade Precision: High-accuracy Magnetic Field Analyzer & Gauss Meter with Advanced Signal Stabilization. > Record, Analyze & Export: track trends with interactive data charts and save detailed logs for professional analysis. 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. DISCLAIMER: - This app is intended for educational and utility purposes. It is not a substitute for certified industrial or scientific equipment. It does not provide medical advice or guarantee "safe zones" in a clinical sense. This app does not guarantee exact measures as other fields can interfere with the compass inside your phone, which is used to detect the fields.
