GhostTube VOX Synthesizer is intended for use and enjoyment on real paranormal investigations and is a suitable substitute or supplementary device for many of the devices used on a typical investigation. But you need to keep in mind that the afterlife is a theoretical concept. It is often categorized as paranormal because the phenomena is not supported or explained by the natural laws of science currently understood and accepted in the scientific community. Paranormal tools in general are designed to measure and react to changes in the environment only. As such, paranormal tools should never be relied on to make important life decisions, as a form of definitive communication, or to cope with grief or loss. Words or sounds generated do not represent the views or opinions of the developer or its affiliates, and they should never be interpreted as instructions or requests.

So far, I don't really know. We have quite some activity in the house here, so using this and your other two apps is interesting, results vary, depending on the days, but I get cool results with the other ghost tube app writing out words. I'd be tempted to get the unlocked version here, but I made the math and decided to wait a little bit.Tonight, as a joke, I said " shave and a haircut!" and a deep voice responded with " MEEP MEEP" like the Roadrunner. Gave me a good laugh, didn't expect that!

I really like the idea for a scary prank on friends or if u just want something to feel more creepy. but the annoying thing about this app is you have to pay to remove distortion, echo and reverb. Which honestly is frustrating consering the voices you can barely understand. I will rate 4/5 just because of the premium thing (I understand, devs need to make money). I would rate 5/5 if we could actually change the sound settings for free.

Thanks for the review. Perhaps we could look to improve the default settings? I will add this to our feature request list. In the meantime, our premium functionality is very affordable (starting at less than a cup of coffee) and unlocks all of the sound controls, custom sound visualizers, filters, languages and more.

I've been using this for a day and have gotten nothing from it. I'm demonically oppressed and have a demon that speaks to me regularly through my phone without an app, and it does not speak to me through this app. Not sure it works. I'll update if that changes. Edit. Changing my rating since I have since gotten some response. My demon prefers to speak through Youtube and Instagram videos, but I got drunk tonight and while speaking with it, decided to open Vox and got a confirmable response.

As the paranormal is theoretical, VOX should be considered experimental. It's designed to measure the environment and react by generating sounds, so relevant responses are never a guarantee. It is not intended to read minds, or contact the dead, but rather react to its environment to be used in an expeirmental way.
