## What is EMF Detector?

EMF Detector turns your iPhone's magnetometer into a precise electromagnetic field scanner with three purpose-built modes — and now keeps a full history of every reading you take.

THREE MODES
• Auto — radial gauge with EMF level descriptions.
• Safety — wire detection (background / weak / moderate / live wire) with reference zones based on ICNIRP public reference levels (safe / caution / danger) and household appliance references.
• Paranormal — baseline-relative anomaly detection. After 5s of baseline measurement, alerts you with 5-level intensity when EMF spikes deviate from normal — classic ghost-hunting workflow.

WHAT'S NEW
• Measurement History — every reading is auto-saved with a 7-day trend chart and insights like "+12% vs your 7-day average".
• Notes & Favorites — add a note ("bedroom wall outlet") and star to any saved reading.
• Compare Mode — pick two saved readings and view the difference side by side.
• Calibration Offset — fine-tune your sensor in ±1 µT steps.
• Share Result — share your current EMF reading as an image.
• CSV Export — share all your measurements as CSV for spreadsheets.

REFERENCE LIBRARY
• ICNIRP public reference level for 50/60 Hz (100 µT), shown for context
• Household appliances: monitor, laptop, electric blanket, fridge, vacuum, induction cooktop, hair dryer
• Wiring: background, weak field, wire detected, live wire
• Paranormal classes 1–5

CORE FEATURES
• Magnetometer-based magnetic field measurement (µT)
• Real-time min/max/avg tracking
• Radial gauge + chart visualization
• Microphone-free, sensor-only

HONEST TECH NOTE
iPhone magnetometers measure static and low-frequency magnetic fields. They cannot detect microwave / Wi-Fi / 5G RF radiation. The app reports what the sensor actually sees.

## Frequently asked questions about EMF Detector

### What can EMF Detector measure?

EMF Detector uses your iPhone's magnetometer to measure static and low-frequency magnetic fields in microteslas (µT). It can detect general EMF levels, identify potential wire presence, and alert to anomalies for paranormal investigation.

### Does EMF Detector have ads?

Yes, EMF Detector contains advertisements. As a free utility app, it relies on ads to support its development and features.

### What are the different modes in EMF Detector?

EMF Detector offers three modes: Auto for general readings with descriptions, Safety for wire detection and exposure zones, and Paranormal for anomaly detection relative to a baseline.

### Can EMF Detector detect Wi-Fi or 5G signals?

No, EMF Detector's iPhone magnetometer cannot detect microwave, Wi-Fi, or 5G RF radiation. It reports only what the device's magnetic sensor can measure.

### How often is EMF Detector updated?

The app was last updated on May 28, 2026, indicating active development. Users can expect ongoing improvements and feature additions.

### What devices is EMF Detector compatible with?

EMF Detector is available for iPhone and iPod devices. It requires iOS to function.

### What is the age rating for EMF Detector?

EMF Detector has an age rating of 17+. This is likely due to the nature of some of its applications, such as paranormal investigation.

### Can I export my EMF readings from EMF Detector?

Yes, EMF Detector allows you to export all your saved measurements as a CSV file. This is useful for detailed analysis in spreadsheets.

## Version history (last 5 releases)

### 1.0.32 — 2026-08-14

The meter was reacting to how you held the phone, not to what was in the wall.

A phone's magnetometer reads the magnets inside the phone itself as well as the field around it, and that internal offset can be ten times larger than Earth's field. The app used to cancel it by taking a single reading at startup and subtracting that number. But the phone's own magnetism stays put while Earth's field swings through the phone as you tilt it — so tilting alone moved the reading by as much as the whole scale. Sweeping a phone along a wall is nothing but tilting, which is how bare drywall could show a red "live wire" warning.

The app now works out the phone's own magnetism properly, by fitting the shape your readings trace as you turn the device. Turn it slowly in a figure-8 for a few seconds when you start and it will say when it is ready. After that, rotating the phone in an empty room barely moves the number at all, where before it could swing across the entire scale.

Also in this update:
• Warnings like "live wire" now wait until the calibration is actually good. Until then you see the reading and a neutral "still settling" label instead of a hazard verdict.
• If the phone's magnetism changes mid-session — a magnetic car mount, setting it on a speaker — the app notices and recalibrates instead of reporting the change as a field forever.
• The guide no longer says the app measures AC magnetic fields. It samples about ten times a second, so 50/60 Hz mains fields, RF, Wi-Fi and radiation are outside what the hardware can do. What it does measure is distortion from ferrous metal, magnets, motors and transformers.
• The ICNIRP figures are labelled as reference levels for context, not a compliance verdict. They are the 50/60 Hz public values, and this app measures a static field, which that guidance treats separately.

### 1.0.31 — 2026-08-06

Ads no longer interrupt you mid-task. Anything full-screen now waits until you have finished what you were doing, and the app stops showing a blank pause where an ad failed to load.

### 1.0.30 — 2026-08-06

Starting a measurement is no longer interrupted — the app gets straight to work, and anything that needs your attention waits until you are done.

### 1.0.29 — 2026-07-30
