About this app

The original Android EMF/EVP detector/recorder. Highest customer feedback and reviews. Don't settle for less on your next ghost adventure.
Your phone has an EMF sensor in it! Use it on your own ghost adventure!

We use your phone's magnetic sensor (electronic compass) to read the local magnetic field and record the results!
This works just like special purpose EMF Detectors that cost up to several hundred dollars, and are used on the paranormal TV shows to find ghosts, except with this app, you can save the results.
Displays and records EMF and EVP data of your surroundings.
Records audio for EVP (Electronic Voice Phenomena) analysis.
Records and saves the EMF readings to a data file that can be displayed in a graph on your phone or computer.
Can also be used to measure and record strong magnetic fields around your home or office.
See website for more information on data file formats.
Optional Enhancement Modules:
- Recording Trigger option. (Android 2.1 and above) Allows setting On / Off trigger values to start and stop recording EMF and EVP.
- Media Enhancement option. (Android 2.2 and above) Adds camera, flashlight, high quality EVP recording (MP4), and immediate EVP playback buttons to the main screen to allow taking pictures, turning on the LED Flashlight without leaving the app, and playback of last EVP while still recording. (Flashlight might not work on all devices)
- Google Drive Integration. Automatically uploads your EMF, EVP Audio and picture files to your Google Drive account. Uploads the EMF (.csv) files as spreadsheets so you can easily graph the results right in the Google spreadsheets program.
- Vibration Detect option. Shows a motion detector icon witch senses slight motion or vibration in your phone. This allows additional methods to interact with entities. The Motion sound can be toggled on/off by pressing the motion icon on the screen.

Use the "Files By Google" app and browse to the "Internal Storage>Documents>EntitySensorPro" folder to see and use files.

Have had this for years but now the magnetic sensor is broken. Avoid this.

I used to love this app! The recording no longer works. I've paid 19.99 when it first came out around 15 years ago and then more for all the add ons. Nothing works anymore! Time to nice on to a different developer. Bummer

What's new

Another change based on errors reported with Google Drive. Google forced us to rewrite this code, so hopefully this will fix it.
