Whether you are a professional Paranormal Investigator, a hobbyist or just want to have some fun, this app works like a "Spirit Box" reading data from your sensors and turning it into spoken words. With a database of over a thousand commonly used words, Ghostalker will read changes in all of the sensors it can find in your device. 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 raw data from the sensors to determine what to say, rather than picking words at random like some other apps. LOGGING: This is the full version of the app so it 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 big a change 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). DICTIONARY: 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, your own custom dictionary or both combined (from v0.5) 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. TIP 1: 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 it 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: NEW - Keep lists of custom words in text files. Each word should be on its own line or separated by a space. Select all of the words and copy them to the clipboard. You can then import them into Ghostalker by pasting them from the clipboard. You can also copy word lists from the web, an email, or anywhere you can copy text. If the app does not do what you were expecting, or there is an issue with it running on your device, please contact us for help. There are no adverts in this software. If you would like to try the free version first (without the logging or custom dictionary functionality), it is listed under "Ghostalker Lite".

GhostAI uses A.I. (a neural net) and your device sensors to build, log & say sentences. Use all available sensors in your device to detect vibration, movement, rotation, and changes in magnetic fields, proximity, light etc. along with custom-built Artificial Intelligence (machine learning) to build sentences. Suitable for professional and amateur paranormal investigators, it is simple enough to use by everyone - even just for fun. NOTE: Do NOT hold, shake or tap your device when using GhostAI. It is specifically designed to detect the tiniest of vibrations. FEATURES include: + Uses the REAL raw sensor data and custom A.I. to build sentences. + Speaks the sentences (using text-to-speech) and logs the sentences to access later. + Includes a built-in log viewer. + Export logs in text/CSV format to use or share in other apps. For example spreadsheets, email, cloud storage. + Turn individual sensors on/off if they receive too much interference or are faulty. + No adverts or in-app purchases. + Does NOT require an internet connection to work. + Does not require any special permissions, apart from GPS access to read changes in movement and storage access to save log files. IMPORTANT INFORMATION to remember: + No information on your device is used to teach the neural net. + Do not expect perfect grammar or sentence structure. By using the real raw sensor data from your device it may not always make sense so you will need to interpret what it says and decide if it is relevant. + Do NOT believe everything that it displays. + If it says anything offensive or bad, consider it interference. + If you are at all worried, turn the app off and take a break. You can always try again later. TIPS: + If it starts to trigger sentences constantly you may be getting interference from something close by. This can include electrical wiring which can cause electromagnetic interference. 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). + If your sensors continue to trigger too much, you can try switching your device into ‘flight’ mode. This will disable all networking features (which GhostAI does not require) but should leave local sensors enabled. + You can see which sensors are being triggered by tapping the “Settings” button. The ones that turn blue are seeing changes above the threshold. If you think a sensor may be faulty or too sensitive, you can tap it to disable/enable it.

Verdict
The clearest difference is rating: GhostAI at 4.0 against Ghostalker's 3.4. Ghostalker's advantage is ratings volume (11 vs 1) and price ($2.99 vs $3.99). On ads, in-app purchases, monetization model and chart position there is nothing between them.

GhostAI holds the better App Store score, 4.0 against 3.4. That said, the two scores are not equally well evidenced: Ghostalker has 11 ratings behind it against 1, so its average is the more settled of the two.
