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.
