Whether you are a professional Paranormal Investigator, a hobbyist or just want to have some fun, this app works like a “Spirit Box” which converts energy into spoken words.
Reached No.1 in the App Store iPad Chart!
(Ghostalker, Ireland, Lifestyle section, 23rd Feb 2020)


Ghostalker is designed to detect the smallest amounts of vibration and movement (along with lots of other sensor readings) and convert those changes into spoken words. This is why it is important NOT to tap, shake or move your device while using the app or it will see that movement as a trigger. If you insist on moving your device or cannot place it on a solid flat surface, tap on the “Sensors” button (under “Settings” in the full version) to turn off the movement sensor, GPS sensor, Gyroscope sensor, light sensor, proximity sensor and rotation sensor – but you will be severely limiting which sensors Ghostalker can use.


With a database of over a thousand commonly used words, Ghostalker will use all of the sensors it can find in your device to pick up changes in energy. This includes sensors for the tiniest amount of vibration, rotation, GPS, gyroscope, light, magnetic fields, proximity etc. and convert them to words which it will display and speak. This app uses the actual data from the sensors to determine what to say, rather than picking one at random like some other apps.

LOGGING (full version only): The full version of the app logs the words spoken for you to view, save, email, delete etc. at a later time. There is also a built-in log viewer. The date and time is logged, along with the combined change in sensor readings (so you can see how much energy was picked up) and the word. The log files are in CSV format so you can import them into your favourite spreadsheet (e.g. MS Excel or Google Sheets).

CUSTOM DICTIONARY (full version only): You can also manage your own custom dictionary of words so you can make your own special list of replies. You can flick between the in-built dictionary and your own custom dictionary at any time.

This app is not designed to form complete sentences so it is up to you to interpret what it says in your own way. Top end phones and tablets tend to have more sensors than low end ones but the app is designed to work with whatever it can find. The sensitivity of sensors will also vary between devices.


Important Guidelines

There are a few things you need to bear in mind when using this app. It is not like other available apps which may appear to be similar but do not make proper use of the sensors available.

  • Do NOT try and use the app while holding your device in your hand. It must be placed on a steady surface to prevent it picking up unwanted movement and vibration.
  • Do NOT lean over your device if it has proximity or light sensors. Your close proximity can cause those sensors to trigger continuously.
  • Do NOT place your device near electrical devices or mains cables if possible. They can interfere with electromagnetic sensors.
  • Place your phone or tablet on a fixed, stable surface before tapping the start screen. It will count down as it calibrates against background sensor readings.
  • Move away from your device once you have started it monitoring. The app is designed to be left alone, some distance from any people. You should still be able to hear any words being said, and the full Ghostalker app will log all entries which you can always look at later.


TIP 1 (full version only): Using the custom dictionary you can have it reply with special limited words, for example ‘yes’, ‘no’ and ‘maybe’ when you ask it questions. Or add a series of digits and get the spirits to pick your lottery numbers. Or add the letters of the alphabet so it can work like a Ouija board.

TIP 2: Paranormal investigators believe that leaving such devices running for as long as possible will allow spirits to learn what energy is required to trigger certain words.

TIP 3: If it starts to trigger words constantly you may be getting interference from something close by. Try moving the device somewhere else or tap the ‘Calibrate’ button to get it to tune out background variance (although you will lose some sensitivity).

TIP 4: If you get a lot of interference causing sensor readings to jump around and trigger words, you can try switching your device into ‘flight’ mode. This will disable all networking features but should leave local sensors enabled.

TIP 5: Save word lists in text files (or Apple Notes or Google Keep) to copy into your clipboard. Each word should be on its own line or separated with a space. Then you can paste them into Ghostalker’s custom word list (full version only) whenever you need them.

If the app does not do what you were expecting, or there is an issue with it running on your device, please contact me for help.

Word Lists

The full version of Ghostalker allows you to switch between the built-in dictionary of over a 1000 commonly used English words, or your own custom word list of up to 10,000 words. With the newest version you can paste words from your clipboard into Ghostalker and it will use those. You can also copy your custom word list into the clipboard so you can paste it into your favourite text editor, notes app or even email to save and use later.

To help get you started we have prepared some custom word lists for you. Choose a list from the drop-down menu below and it will automatically copy the words into your clipboard*.

“I downloaded this app expecting to be disappointed and ultimately uninstall. I find myself to be an expert on apps that are fake or capable of providing legitimate results. This one is legit. Yes, some words are not relevant and will pop up just due to a surge in emf. Use airplane mode, then place on a solid surface and calibrate. Using airplane mode will eliminate false positive results.”
