## EMF Field Detector RF Scanner Description
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.

Download now and start discovering the hidden electromagnetic activity around you.

## EMF Field Detector RF Scanner Reviews in United States

### ***** "Amazing"
It's not only the best interface of any app I've seen but it functions so simply with surprising accuracy. It's the first time I've seen function and fun combined and synced with functionality.
-- Mbammyy, 2024-12-21

### ****- "Easy to Read"
The EMF display is clean and easy to read, which is nice to stay focused. It’s helped me locate congested areas and deconflict the noise, strengthening other signals so the airwaves are cleaner.
-- Byte-Dr, 2024-12-17

### ***** "Works Great!!"
This app has helped me out quite a bit. I now know where the problems are in our house, work etc!
-- THEUNDERATER, 2024-12-08

### ***** "EMF research"
I really don’t know much about EMF but I needed to test a place in my house. The video that they showed me allowed me to understand and correctly use the app.
-- Girl mike82, 2024-12-08

### ***** "So far so good"
What I’ve seen so far is that it does a good job of picking up EMF energy when the phone is directly over the area.  Excited to explore more with it.
-- Cosmic Vibes Guy, 2024-11-26

### ***** "EMF Detector"
Great app for measuring, very accurately, surrounding EMF radiation.  Had for just a few days and am enjoying the app checking out my house for sources of EMF.
-- Deaconalso, 2024-11-26

### ****- "Great place to start"
I was surprised to find that this wasn’t a gimmick. I have consistent readings in the same areas with many other variable changed. 
I’m using this as a starting point with confirmation by professionals with mitigation to follow.
-- ~~~MrTony, 2024-11-19

### ****- "Good value"
Good value
-- Millerf11, 2024-11-10

### ***** "Excellent but to many ads... overly done"
It’s a great app. Helps me see where there is a hot area of electro magnetic energy. This has helped me from finding the right spot for my wifi with minimal interference, identifying object to remove from the bedroom for healthy sleep, all the way to creating a meditation spot and paranormal hunting.
-- lantheflan, 2024-11-03

### ***** "Works well nice ui"
I like the app
-- GJBET, 2024-10-24
