EMF Detector (Scanner) vs Real EMF Detector

EMF Detector helps you visualize Electromagnetic Field (EMF) activity around you using your iPhone’s built-in magnetometer. Whether you are checking electronics, exploring your environment, or tracking unusual magnetic changes, EMF Detector provides a clear and easy-to-read real-time experience. KEY FEATURES • Real-time EMF meter with smooth, responsive updates • Live waveform and graph views for continuous monitoring • FFT view to inspect frequency components of signal changes • Signal change detection to catch sudden spikes and drops • Measurement history so you can review previous sessions • Export options (such as PDF and video capture) for sharing and reporting • Sound effects and feedback options for interactive monitoring • Clean, intuitive interface designed for quick readings USE CASES • Scan around household electronics • Compare magnetic activity in different rooms • Observe signal behavior near cables, adapters, and devices • Record and share findings for personal reference IMPORTANT NOTES • This app is for general informational and educational use. • Because this app uses your phone’s built-in sensors, readings may vary depending on your device specifications, device condition, and surrounding environment; use all measurements for reference only. Upgrade options may be available for additional features and an enhanced experience.

Measure magnetic fields with real sensor data. Real EMF Detector turns your iPhone into a precision magnetometer using the built-in calibrated magnetic field sensor to detect and measure DC magnetic fields around you. CALIBRATED SENSOR TECHNOLOGY - Uses Core Motion calibrated magnetic field data that removes device self-interference - X, Y, Z axis breakdown showing directional field components - Total field magnitude in microtesla with continuous updates - More accurate than raw magnetometer apps that include phone hardware noise REAL-TIME DETECTOR - Large circular gauge with smooth animated needle - Color-coded safety levels: Background, Normal, Elevated, Strong, Very Strong - Instant response as you move through your environment - Configurable threshold alerts with haptic feedback LIVE GRAPH - Real-time scrolling chart built with Swift Charts - Track magnetic field changes over time as you scan - Pinch to zoom and scroll through recorded data - X, Y, Z axis overlay for detailed field analysis STUD & METAL SCANNER - Detect metal objects, pipes, and wiring behind walls - Find studs by scanning for nail and screw patterns - Audio and haptic feedback as field strength changes - Sensitivity adjustment for different scanning needs SESSION HISTORY - Record complete measurement sessions with one tap - Review past sessions with full statistics and timeline - Export session data as CSV for further analysis - Stored locally with SwiftData for fast access LEARN & UNDERSTAND - Educational guide to magnetic fields and EMF science - Understand what your readings mean in everyday context - Reference chart comparing common magnetic field sources - Safety information based on published exposure guidelines COMMON USES - Home inspection: check appliances, wiring, and electrical panels - Stud finding: locate metal fasteners behind drywall - Education: learn about magnetism and electromagnetic fields - Hobby and exploration: investigate unusual magnetic sources - Workplace assessment: identify strong field areas HONEST ABOUT LIMITATIONS Real EMF Detector measures DC magnetic fields using the iPhone magnetometer. It cannot detect RF signals, Wi-Fi, cellular (5G/4G), AC electromagnetic fields, or electric fields. For those measurements, specialized equipment is required. What it does measure, it measures well -- with calibrated data that most competing apps lack. Built with SwiftUI, Swift Charts, and Core Motion. No ads, no data collection.
