Description
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.
