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. IMPORTANT: Do NOT hold your device and do NOT shake or tap your device while running Ghostalker LITE. It is designed to detect the smallest movements and vibration, as well as changes in electromagnetic fields, light, proximity etc. With a database of over a thousand commonly used words, Ghostalker Lite 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 one at random like some other apps. TIP 1: 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 2: 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 3: Occasionally interference can cause individual sensors to trigger constantly. This can also be caused by faulty or overly sensitive sensors. From v0.2 you can now enable and disable individual sensors to prevent such issues. The LITE version of Ghostalker shows the last 10 words spoken but does NOT log those words, it does NOT include the log viewer, and it does NOT allow you to create a custom dictionary of words. If you like this app and want these extra features, please download the full "Ghostalker" app. 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 hardware it can find. The sensitivity of sensors will also vary between devices. 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. There are no adverts in this software and it does not require an Internet connection.
