What’s an EMF Detector App?
Going the EMF route is a cost-effective way to get rid of electromagnetic field radiation around you. While EMF shielding experts still recommend using EMF meters to determine the amount of EMF in an area, these apps can do the same at a lower price or even for free. Simple animation app mac.
An EMF detector app is a dedicated software that can easily determine the amount of EMF in a given area. This app can process and determine the amount by using your smartphone’s feature to send and receive radio frequency waves. Other EMF detection apps make use of your smartphone’s magnetometer to help detecting the presence of electromagnetic field radiation.
Recommended Features
Choosing the right EMF detection app for you will be easy. Google’s Play Store and the AppStore both offer a wide variety of choices. They all come with a unique feature to set them apart from the competition. However, these are the following features most sought by EMF shielding professionals:
Ability to recognize and interpret EMF and other forms of radiation
Pick an app that is capable of providing you real-time reading. It will ensure that you are getting an accurate amount of EMF present in the area. Additionally, do get an app that does not only measure electromagnetic field radiation. Look for one that allows you to review past readings, and additional feature like detecting an electronic voice phenomenon.
Warning sound
This feature is also recommended by EMF shielding professionals when getting an EMF meter. This feature will allow you to search for places where there is possible EMF presence. Usually, people who are looking for EMF presence have their attention on the display of the EMF meter or app.
A warning sound integrated with the EMF detection app will allow you to look around the space and determine where is the best spot EMF is coming from.
Precision of EMF reading
Professionals still recommend using a professional-grade electromagnetic field radiation meter. However, development of EMF detection apps is advancing rapidly to keep up with the abilities of a traditional EMF meter. It is best to read reviews to check whether those mobile EMF measuring apps on app stores are precise in their readings of EMF and other radiation present in your surroundings.
Why Should I Use One?
EMF is a hazard not only to your health, but to everyone and everything around you. Your health is its number one target. Medical researchers have continuously studied the impact of EMF pollution on the human health. Many of the studies concluded that EMF and other forms of radiation significantly contribute to the development of various serious health issues. On human, scientists have found that constant and prolonged exposure to EMF, radio frequency waves and other forms of radiation can lead to the following:
- Cancer
- Low birth weight
- Changes in sleep quality and pattern
Plants and pets are also affected by EMF exposure. They are also not spared from the impact of this pollution. Given the power and capability of EMF radiation, it can affect their growth and even threaten their survival. The following are some findings from studies that looked on how EMF affects animals and plants:
- Lymphoma in dogs – a study from the Colorado State University disclosed that there is a direct correlation between constant exposure of a pet dog to EMF and the development of lymphoma. It further explained that the dogs observed were subjected to EMF coming from high-voltage power lines near the pet dogs’ home.
- Dog behavior – a study from 2013 found that dogs defecate based on the planet Earth’s certain electromagnetic field. Researchers concluded that dogs normally defecate and urinate with their bodies aligned to the north-south axis.
- Marine animals – even fish and other marine animals are not spared from the impact of EMF. The growing adoption of Internet made undersea cables a must to keep everyone connected at all times. However, the growing number of underwater cables significantly affects marine life. Some of the sea creatures usually depend on electromagnetic field to find their way under the sea. EMF from underwater cables can impact how they move around underwater.
Top Picks
Choices may be abundant, but EMF shielding experts recommend the following for standing out from the competition. These apps were also found to have integrated the most recommended features and were tested to ensure that they are all capable of determining the amount of electromagnetic field radiation in a space.
Electromagnetic Detector: EMF Scanner
This EMF scanning mobile app is the top ranking among EMF detection apps in Apple’s AppStore. Based on testing, the Electromagnetic Detector was able to detect radio frequency radiation in the area measured. However, it was not able to provide the same readings that came from the TriField TF2 EMF meter. Despite not providing the same readings as that from the TF2, the mobile app provided a close reading to that of the EMF meter.
Entity Sensor Pro-EMF Detector
Android users are not left behind. The Entity Sensor Pro-EMF Detector is the most favored among experts if you are using an Android smartphone. This app features the ability to read and analyze EMF, the ability to save readings, an option to save the readings on Google Drive, and is available in three languages – English, Simplified Chinese, and Traditional Chinese.
The Entity Sensor was able to produce an accurate reading of EMF presence after testing it. However, developers said readings is limited given that the app depends on internal hardware compass of your smartphone. This limitation can affect readings at some time.
Ultimate EMF Detector
The Ultimate EMF Detector comes with a simple interface so you can easily determine the amount of radiation in a given space. This app from the Google Play Store and makes use of your smartphone’s magnetic sensor to determine the amount of EMF.
Developers of the apps warn that your smartphone should have a built-in magnetic sensor. Lack of such sensor will make the app useless in detecting EMF and other radiations. Features of this app includes magnetic field readings in microTesla, Gauss, and milliGuass, and an EMF meter display that has a needle and a numerical output. Download tsheets on desktop. The Pro version of the app includes a sound notification, and various skins for the app.
Entity Sensor Pro – EMF Detector
Night mode mac app. The Entity Sensor Pro is a Gauss meter app. It is capable of measuring magnetic field radiation. Its features include automatic recording of electromagnetic field radiation and electronic voice phenomenon (EVP). The app comes with a display both EMF readings and EVP around a given space. The paid version of this EMF detection app a button that starts and stops recording of EMF and EVP and media enhancement that allows integration of camera, flashlight, and high-quality audio recording.
Go Get an App
If you have a smartphone, getting an electromagnetic field radiation measuring app is the best option. It is the most acceptable alternative to having an EMF meter. While many EMF shielding experts expressed concern on some apps available on the Google Play Store and the iOS AppStore, there are those that performed well in testing.
The need for this kind of app comes from the fact that EMF is all around us. Studies found that it is a health hazard not only to humans, but also to plants and animals. Researchers revealed that it causes cancer, changes to sleep quality, and brain activity in humans. Animals and plants were found to be threatened by EMF exposure.
Dogs who were constantly found exposed to high-voltage power lines developed lymphoma according to a study. Marine animals were also discovered to suffer from the prevalence of EMF radiation. Medical professionals can’t emphasize enough the importance of prevention to protect yourself from any kind of health issue.
Having an EMF scanning app is the best prevention when it comes to electromagnetic field radiation exposure. It can allow you to devise ways to get rid of items causing too much amount of EMF in your surroundings.

Audio Frequency Counter
from KEUWLSOFT
Frequency counter based on the microphone input. Counts when the input rises or falls past a set level and converts into into frequency or a time period. FOR INDICATION ONLY. Results depend on your device and its hardware. If you just want to know the frequency of a sound with harmonics (e.g. mucial instrument), a FFT based app such as keuwlsofts spectrum analyser, harmonicity meter or guitar tuner will be better. This app can provide more accurate frequency measurement for single frequency input signals.
Features of this audio frequency counter:
• Graph of input signal, 2.5 ms/div up to 640 ms/div.
• Gate time of 0.1s, 1s, 10s or 100s.
• Gain from x1 to x1000
• Trigger on rise or fall
• AC or DC coupling
• Settable noise level so new event is not triggered until the signal has first passed this level.

Using the App
Once loaded the app will immediately start counting events when the signal passes the trigger level threshold. The frequency or time period will be shown at the top of the display followed by a count of the triggered events. Below the count value is a graph showing recent traces (new trace will only start on a triggered event). The most recent trace on the graph is shown in cyan. The previous 3 or 4 traces are shown in fading grey colors to show how the signal is changing.
Below the digital display, there are 8 groups of buttons:
Measure - Select either FREQuency or time PERIOD to be displayed. Frequency is just the reciprocal of the time period:
Below the digital display, there are 8 groups of buttons:
Measure - Select either FREQuency or time PERIOD to be displayed. Frequency is just the reciprocal of the time period:
Control - Tap Zero to reset the count. Tap pause to pause the measurement. Tap pause again to continue.
Gain - Use the left and right arrows to adjust the gain up or down. 10 different gain values are available: x1, x2, x5, x10, x20, x50, x100, x200, x500 and x1000. The current gain value is shown below the graph.
Time/Div - Use the left and right arrows to adjust the time per division up or down. The shortest value is 2.5 ms/div and since there are 8 division, the whole trace will be 20 ms of data. the time per division can be 2.5 ms/div, 5 ms/div, 10 ms/div, 20 ms/div, 40 ms/div, 80 ms/div, 160 ms/div, 320 ms/div or 640 ms/div. Note that the app will always sample at 44.1 kHz and the time/div only reflects what is displayed on the graph. Note that at 80 ms/div or above, the trace will roll across the screen. At 40 ms/div and below, the whole trace is first captured before displayed.
Threshold - Set the threshold level and noise level from which to trigger off. The trigger level value can range from -100% to 100% and is selected by the slider or from entering the value after pressing the level button. The trigger level is shown as a red horizontal line on the graph. In rise trigger mode, when the signal goes from below to above this line, an event is counted. In fall trigger mode, an event is registered when the signal goes from above to below this line. To avoid false counts due to noisy signals, a noise level can also be set. After registering and event, the signal must first pass back over the blue noise level before another count will be accepted. The noise level can be set with the slider, or the Noise button and values can range from 0 to 100%.
Direction - Select either to trigger off a rise in signal over the threshold or a
App Macos Measure Frequency Modulation
fall in the signal over the threshold. Depending on the waveform shape, one direction may trigger more cleanly and give more stable results.App Macos Measure Frequency Chart
Coupling - Set the coupling to AC or DC. In DC mode the signal is unadjusted to that measured from the microphone input. In AC mode the long term average is removed from the signal. If your device input is not symmetric about the zero value, AC mode can remove an offset. If you want to measure very low frequencies, DC mode should be used.
Gate Time - The frequency and time period will be calculated from this length of data accumulated. If there less data that the gate time (i.e. zero pressed or app just started) then the data gathered so far is used. The gate time can be 0.1s, 1s, 10s or 100s.
Triggering
The following diagram illustrates triggering with and without the noise level:
Macos App Download
The red line is the trigger level and the green dots show where an event was triggered. In the first diagram, no allowance for noise means that for noisy signals, multiple triggered events can occur for each waveform. The second diagram shows a noise level indicated by the blue line. This blue line must first be crossed before another event can be triggered. In this case, with a suitably selected noise level, only one trigger event is registered for each waveform.
Some further consideration
The app samples at 44.1 kHz (typical audio sampling speed). The actual sample rate may vary depending on the clock speeds controlling the audio input. The actual sampling speeds are therefore likely to vary from device to device. Temperature of the device is also likely to affect the clock speed by a small amount. The maximum detectable frequency is ~22kHz with the threshold being crossed every data point.
