## What is EMF Field Detector RF Scanner?

Turn your iPhone into a powerful EMF detector and magnetic field scanner.

Detect electromagnetic fields (EMF) around you instantly using the built-in sensor already inside your device — no expensive equipment required. Whether you want to monitor electromagnetic radiation in your home, locate hidden magnetic sources, or even explore paranormal activity, this app gives you a simple and exciting way to measure the invisible world around you.

Use the app to scan bedrooms, walls, electrical appliances, Wi-Fi zones, sockets, microwaves, wireless devices, and more. Discover areas with unusually high magnetic activity and receive an instant warning beep when strong EMF levels are detected. Many users also enjoy using the app during ghost hunts and paranormal investigations, as sudden magnetic fluctuations are often associated with supernatural activity.

NEW: Experience EMF detection in Augmented Reality.

Visualize electromagnetic fields in Augmented Reality to better understand how EMFs spread throughout your home, office, or workspace. The app allows you to see a figurative representation of magnetic activity around you, helping you identify high-radiation zones and understand how far electromagnetic fields may reach in real-world environments.

Explore EMFs in a more immersive and intuitive way by combining real-time detection with AR visualization technology.

Transform your iPhone into a digital EMF Meter, Teslameter, or electromagnetic field tester using the internal compass hardware. View live magnetic field readings in real time and monitor changes on all three axes (X, Y, Z).

Scientists, engineers, students, teachers, paranormal investigators, and curious explorers use EMF detectors to measure magnetic activity in everyday environments.

Why use this app?
• Detect high electromagnetic field zones around you
• Monitor EMF levels near beds, appliances, or workspaces
• Receive warning alerts when strong magnetic radiation is detected
• Track and store measurements with time and date stamps
• Investigate unusual magnetic fluctuations during ghost hunting sessions 
• Find metallic objects, pipes, or hidden sources behind walls
• Explore the invisible electromagnetic world around you

Features:
•  Real-time EMF and magnetic field detection
•  Warning beep near strong radiation sources
•  Measures magnetic force on X, Y, and Z axes
•  Magnetic readings displayed in microteslas (µT)
•  Save up to 100 EMF records
•  Record events with exact date & time
•  Export and send measurements by email
•  Easy-to-use digital display interface

Electromagnetic radiation may come from electrical wiring, appliances, wireless devices, cordless phones, Wi-Fi equipment, sockets, and other electronic sources in your environment.

Tips:
For best accuracy, calibrate your iPhone by moving it in a figure-8 motion before use.

Important:
This app requires an iPhone with compass hardware and will not work on iPod Touch devices.

Disclaimer:
This app is intended for entertainment and informational purposes only. It uses the iPhone magnetometer sensor to detect magnetic field variations near ferromagnetic objects and electromagnetic sources.

### 5/5 — Very interesting app

*2026-07-14, version 7.4*

I am intrigued to continue using the app.

### 1/5 — A joke

*2026-05-11, version 7.1*

Values don’t change as you drive from downtown into the deep national forest with no signal around, meaning those values are random and not real

### 1/5 — Not good

*2026-04-13, version 6.9*

Unable to locate any type of devices with this app.

### 5/5 — Pretty Handy

*2026-03-13, version 6.9*

App is cool. Still working it out but it pretty good so gar.

### 4/5 — Good app

Seems accurate. Pretty handy to have on my phone. I use it multiple times a day.

### 5/5 — Easy, straight to the point, and accurate

*2026-03-08, version 6.9*

This app has validated my concern for possible high emf levels, which is very concerning because it’s right where I sleep. I installed the app, set it down and right away, the alarm on the app started going off.

### 5/5 — Handy tool for everyday monitoring

*2026-03-06, version 6.9*

I like to use this app when I am around other electronics  to see how strong the RF radiation is and how it may affect my job

### 1/5 — Not good

*2026-02-24, version 6.9*

Such a waste of money. Not helpful

### 5/5 — Very Informative

*2026-02-17, version 6.9*

So far, the app has performed quite well. I’m looking forward to all that this app has to offer.  It’s responsive and informative without being confusing.  It sparks my desire to learn more!

### 5/5 — Audio EMF

*2025-12-16, version 6.9*

I build esoteric audio vacuum tube amps and EMF is very important in the placement of transformers and chokes. I’ve also used this App in discovering a problem with placement of our ONT for the optic fiber WI-FI that Frontier couldn’t solve. Great App!!
