Turn your iPhone into a powerful EMF detector and magnetic field scanner. Detect electromagnetic fields (EMF) around you instantly using the built-in sensor already inside your device — no expensive equipment required. Whether you want to monitor electromagnetic radiation in your home, locate hidden magnetic sources, or even explore paranormal activity, this app gives you a simple and exciting way to measure the invisible world around you. Use the app to scan bedrooms, walls, electrical appliances, Wi-Fi zones, sockets, microwaves, wireless devices, and more. Discover areas with unusually high magnetic activity and receive an instant warning beep when strong EMF levels are detected. Many users also enjoy using the app during ghost hunts and paranormal investigations, as sudden magnetic fluctuations are often associated with supernatural activity. NEW: Experience EMF detection in Augmented Reality. Visualize electromagnetic fields in Augmented Reality to better understand how EMFs spread throughout your home, office, or workspace. The app allows you to see a figurative representation of magnetic activity around you, helping you identify high-radiation zones and understand how far electromagnetic fields may reach in real-world environments. Explore EMFs in a more immersive and intuitive way by combining real-time detection with AR visualization technology. Transform your iPhone into a digital EMF Meter, Teslameter, or electromagnetic field tester using the internal compass hardware. View live magnetic field readings in real time and monitor changes on all three axes (X, Y, Z). Scientists, engineers, students, teachers, paranormal investigators, and curious explorers use EMF detectors to measure magnetic activity in everyday environments. Why use this app? • Detect high electromagnetic field zones around you • Monitor EMF levels near beds, appliances, or workspaces • Receive warning alerts when strong magnetic radiation is detected • Track and store measurements with time and date stamps • Investigate unusual magnetic fluctuations during ghost hunting sessions • Find metallic objects, pipes, or hidden sources behind walls • Explore the invisible electromagnetic world around you Features: • Real-time EMF and magnetic field detection • Warning beep near strong radiation sources • Measures magnetic force on X, Y, and Z axes • Magnetic readings displayed in microteslas (µT) • Save up to 100 EMF records • Record events with exact date & time • Export and send measurements by email • Easy-to-use digital display interface Electromagnetic radiation may come from electrical wiring, appliances, wireless devices, cordless phones, Wi-Fi equipment, sockets, and other electronic sources in your environment. Tips: For best accuracy, calibrate your iPhone by moving it in a figure-8 motion before use. Important: This app requires an iPhone with compass hardware and will not work on iPod Touch devices. Disclaimer: This app is intended for entertainment and informational purposes only. It uses the iPhone magnetometer sensor to detect magnetic field variations near ferromagnetic objects and electromagnetic sources. Download now and start discovering the hidden electromagnetic activity around you.

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.
