This simple-to-use tool takes advantage of your phone's magnetic sensor to translate fluctuations in the local electromagnetic field (EMF) into readable text and audio output. The controls allow you to fine-tune the sensitivity of the sensor and calibrate the live graph displaying the changes in the EMF. When your trigger threshold is breached, the app's algorithm translates the signal into an english word from a carefully selected lexicon of 100 words. A synthetic voice, which reads the selected word aloud, can be toggled ON or OFF for your convenience.
How To Use This Tool
Begin by opening the app and placing your phone on a dry, flat, unmoving surface. Press the "SET BASELINE" button to take an initial reading that is used to compare against the continuously updated EMF reading. Next select whether to toggle ON or OFF the synthetic voice and/or "printing" of the words selected from the lexicon. Printed words will appear at the bottom of the screen. Next you may select the sensitivity of your trigger, measured in microteslas. Finally, press the "PRESS TO START" button to begin scanning.
Reading The Graph
While the sensor is activated, your graph will draw a teal-colored line from left to right. This line represents the difference in magnitude between your baseline reading and the current EMF signal detected. When the line reaches the right side of the graph, it will reset to the left side and continue drawing to the right. If your measurements go offscreen either on the top or bottom, they will be made red to indicate clipping. A hit is indicated by a yellow dot, and if your voice and text are toggled to ON, this will be accompanied by a word from the lexicon.
Tips And Tricks
Ideally you should set the trigger to the highest rating (20 microteslas) to avoid interference from noise in the local EMF. This ensures that only the strongest spikes in EMF disturbance can trigger a hit. However if there is little electromagnetic disturbance in your location, you can reduce this trigger threshold to target "quieter" attempts at contact. If you aren’t experiencing any hits in a known active area, try increasing the sensitivity of the trigger. If you choose the most sensitive trigger rating (0.1 microteslas) you may receive a constant stream of "hits." This indicates a high level of noise. However, you may find this setting useful as a sort of "automatic writing" (psychography) interface.
It is recommended that you keep your phone stationary as movements can cause false signals. Also, avoid any electrical appliances or devices as these too can produce false signals. If your graph line clips at the top or bottom and turns red, reduce the "GraphY Scale" to increase the amount of room above and below the baseline reading.
Different devices have different magnetic sensors and settings. These sensors are often directional, and may be oriented differently from one device to another. This could cause two devices with the same settings to produce differing results. It may be necessary to use one calibration for Device A and a different calibration for Device B. Placing multiple devices in close proximity to each other may skew results. Do not expose your device to high powered magnets as this will produce false signals and could potentially damage your device's magnetic sensor as well as other parts of the device.
Most importantly, have fun and be safe!
