Easy, straight to the point, and accurate

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.

FAQ

What does the EMF Field Detector RF Scanner app do?

This app allows you to detect electromagnetic fields (EMF) and magnetic radiation using your device's built-in sensors. It can alert you to high magnetic field measurements and potential radiation sources around you, such as appliances or electrical outlets.

What are the key features of this EMF detector app?

Key features include tracking high magnetic field measurements with time stamps, receiving warning beeps near radiation, measuring magnetic force on three axes (x, y, z) in microteslas, recording up to 100 readings, and the ability to send measurements via email.

Is this app free to use?

The app is available for free download and use, but it includes in-app purchases. This means you can use the core functionality without cost, but certain additional features or enhancements may require a purchase.

What devices is this app compatible with?

This app is designed to work with iPhones that have compass hardware. It will not function on an iPod Touch as it lacks this necessary component. It's important to note that the app is intended for entertainment purposes and does not provide true metal detector functionality.

How can I use this app to check for EMFs?

You can use the app to scan your surroundings for electromagnetic fields. Place your device near appliances, electrical sockets, or other potential sources of radiation. The app will alert you to high readings and allow you to record them for later review.
