It requires a leap of faith to use an app on a mobile phone to detect or communicate with spirits. There is no requirement for an app in either the Apple App Store or on Google Play to prove its claims and ability to contact the dead, but there are some apps available on Android and iPhone which are better than others and at the very least are worthy of some investigation.
Using any kind of electronic device to communicate with the dead is known as Instrumental Trans Communication (ITC). There are a few ways that ITC apps work. It can either be through electronic speech synthesis apps, or by measuring atmospheric conditions via electronic methods.
The apps which rely on speech synthesis tend to include a database of words or phonics. An algorithm generates a random number which is associated with a word. The claim is that spirits can affect the random nature of the apps and allow them to select words in order to communicate with the app’s user.
Below is a list of the best ghost hunting and ITC apps available for iOS and Android for use on vigils and investigations. Because of the unproven nature of the paranormal, most of these apps are provided for entertainment purposes only. Their developers do not guarantee or deny the existence of ghosts or paranormal activity.
SensorLab has access to all of the device’s sensors and shows realtime data, this includes things like GPS location, sound level, light meter, memory usage, step counter, and network usage and strength, but these aren’t the interesting sensors, the ones which can approximate ghost hunting gadgets are:
• Battery temperature, current and level
• Pressure (hPa)
• Magnetometer (x, y and z axis)
• Compass (azimuth)
• Accelerometer (x, y and z axis)
• Gyroscope (x, y and z axis)
The best way to use this app is in the same way as any other app. Simply place it on a flat surface in the area you are investigating and call out to any spirits that might be present and encourage them to interact with the device. If they are able to then this might present itself as a spike in one of the metrics. If spirits can manipulate this raw data, then this means some of the other apps on this page could also work effectively.
The app has been used by various paranormal investigation teams, including those featured in ghost hunting television shows like ‘Ghost Chasers’ and ‘Ghost Hunters International’. EchoVox is one of the most expensive paranormal apps of its type, but is available to download for both Android and iOS devices.

The app uses as many of the phone’s input methods and sensors as possible, in order to provide detailed analysis of audio signals, allow you to track subtle changes in the ambient barometric pressure, and measure electromagnetic field strength based upon your phone’s magnetometer.
The app can also act as a very sensitive vibration detector to visualise and alert you to tiny knocks and taps. There’s even a Spirit Box feature, that rapidly scans through live-streaming audio channels, unlike the physical devices that scan through FM radio frequencies. The idea is that spirits can communicate by manipulating these sounds.

When the app starts up it generates a large string of random numbers. The app’s internal algorithms translate this string into all of the stats that are displayed on the screen. The basic premise is to test whether random algorithms may or may not be influenced by forces beyond our current understanding.

There’s also a spirit box feature which scans through a sound bank of over 3,000 pieces of audio taken from AM, FM and other radio frequencies, as well as phonetic audio, and several other sources. The app also has a purpose-designed digital audio recorder which will help you capture spirit voices in the form of electronic recordings, a principle known as electronic voice phenomenon (EVP).

When one of the device’s sensors is triggered, it creates a marker in the audio bank, this piece of audio will be heard if a sensor is triggered again. If the device is triggered multiple times then full words and sentences can naturally form.
The app’s developers say that they believe that paranormal entities are able to trigger the sensors in a mobile phone in order to form the words it wants to communicate.
The Witch II
The app randomly fires one of the eight banks, a random sweep rate is picked along with a random volume every time a bank fires. This new app has a darker design, which its developer says might also attract darker energies.
The audio recorder, which is a standard feature of most phones, will allow you to record an audio log of your investigation and listen back and review it. Many investigators often find they’re able to capture alleged spirit voices in these recordings, this is a method of spirit communication known as Electronic Voice Phenomenon (EVP).
