Features & Capabilities

Turn your iPhone into a precision magnetometer. Real EMF Detector provides calibrated readings, real-time graph, stud scanner, session recording, and safety-level alerts.

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.
