## 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.
