The EMF Sensor utilizes your phone's built-in magnetic field sensor to take electromagnetic field (EMF) readings. It operates similarly to a 3-axis EMF meter and displays the measurements in milli Gauss (mG) or micro Tesla (uT).
This app provides a customizable graph with optional auto-ranging capabilities for the displayed data. It is particularly useful for various applications such as:
Ghost hunting
Paranormal research
Locating sources of EMF radiation
Monitoring EMF levels
Satisfying curiosity about EMF exposure
Additionally, it includes an EVP (Electronic Voice Phenomenon) function that allows live audio graphing and recording.
The app offers the ability to graph and record live audio data. Once recorded, you can edit the audio by creating clips and exporting them for further use.
For detailed instructions on how to utilize this feature, refer to the menu within the app.
To adjust preferences, simply press the menu button where you'll find several display options available for customization.
Adjusting the Meter Range
You can change the range of the meter via the options menu or by sliding your finger up or down on the screen. The left section adjusts the minimum value, while the right side modifies the maximum value.
Touch Adjustment Lock
You have the option to lock or unlock touch adjustments through the menu.
Auto Range Mode
This function can be selected to affect either the graph range, the UI range, or both. For optimal experience, it's recommended to select both Graph and Interface for fully automated range control.
Baseline Mode
Set a baseline value that will be subtracted from the readings for better analysis.
Custom Color Options
Users can customize text and graph line colors based on their preference.
Sound Settings
An audio feature can be enabled and customized in preferences (default is off). This setting emits a tone corresponding to the EMF reading rate, similar to how a Geiger counter operates.
If you have any questions, comments, concerns, or ideas regarding the app, please feel free to reach out via email, as this is the best way to communicate issues you may encounter.
This app has been designed to be lightweight, fast, and free of unnecessary gimmicks. Enjoy your EMF exploration!
