Can an iPhone Be Used as an EMF Detector

Exposure to electromagnetic field (EMF) radiation is damaging to human health. And the higher the exposure, the greater the risk of damage. EMF radiation cannot be seen or touched. There’s no way to know you are being exposed to the radiation unless you go out of your way to detect its presence.

It will surprise you to find that mobile phones, such as iPhones and Androids, can detect EMF radiation. Although this may seem counterintuitive since mobile phones themselves emit high-levels of EMF radiation, they also have downloadable apps that serve EMF meters’ functions.

This article contains information on EMF testing and some of the best mobile phone apps that are efficient EMF detectors. Read on if you want to learn more.

What is EMF Testing?

The exponential increase in the number of EMF-emitting technologies in our environment has increased concerns over the health risks associated with EMF radiation. This has prompted a lot of people to ask the question: What is EMF testing?

In simple terms, EMF testing refers to testing for the presence of EMF radiation and the magnitude in which it is present. To carry out EMF testing, you need to use a device known as EMF meter, which measures EMF.

Why Do You Need to Conduct EMF Testing?

What is EMF Testing

The amount of EMF in our environment increases every day, thereby exposing humans and even animals to its dangers. It is also impossible to feel or see this radiation and know when one is being exposed to it. This increases the risk because there’s no way you can escape it if you don’t know where it is coming from and how you are being affected by it.

This renders it imperative to conduct EMF testing as it will help to determine the source of this harmful radiation if you are being exposed to it, and the rate of exposure. If you can acquire this information, then you’d be able to determine the best way to protect yourself from the increasing rate at which EMF is being emitted from your surroundings.

EMF testing is also useful during a move. For instance, if you are planning to buy a new house or rent a new apartment, you can conduct EMF testing on the new locations to determine the EMF level present in the home.

EMF Detector Apps

An EMF detector app refers to dedicated software that can determine the EMF level in a particular area. It achieves this by transmitting and receiving RF waves through the smartphone’s features. Some EMF detector apps employ the smartphone’s magnetometer in detecting the presence of EMF radiation.

There are several choices of EMF detector apps available for download on Google Play Store (for Android devices) and AppStore (for iOS devices), which makes choosing the right EMF detector app a bit of a task. However, each of these detectors has specific features that distinguish them from one another. The following are some of the features you need to look out for in your search for the right EMF detector app:

  • Ability to identify and interpret EMF and other forms of radiation

Ensure that the app can provide a real-time reading of what it measures. This will enable you to achieve an accurate measurement of the amount of EMF radiation in the environment. Also, ensure that the app can measure other forms of radiations along with electromagnetic field radiation. Look out for apps that allow you to review your previous EMF readings as well. An additional feature is the ability to detect electronic voice phenomena.

  • Warning sound

This feature is an important one to look out for when acquiring an EMF meter. The warning sound enables you to locate the places with possible EMF presence with ease. If your app lacks the warning sound feature, your eyes will be fixated on the app’s display instead of the surrounding, which means you will have to search around the area to identify the specific area the EMF is located in. In contrast, an EMF detector app with a warning sound will enable you to easily determine the best spot where the EMF radiation is being emitted.

  • Precise EMF reading

Although EMF detector apps are rapidly advancing to keep up with the traditional EMF meter capabilities, they are not yet able to provide functionalities that are as efficient as that of traditional EMF meters. Hence, professionals are prone to recommend using a professional-grade EMF meter for EMF testing. You have to read the reviews of each EMF detector apps you want to download to determine whether they are accurate with their measurements of the amount of EMF radiation and other forms of radiation available in your area.

Best EMF Detector Apps

Best EMF Detector Apps

The following is a list of some of the best EMF detector apps available for download on Android and iOS devices:

1. Electromagnetic Detector: EMF Scanner

The Electromagnetic Detector: EMF Scanner is one of the best EMF detector apps available on iOS devices. It enables you to convert your mobile device into an EMF meter as it uses the internal compass hardware of your device to identify the EMF radiation around you.
