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.

It's a lot of fun to play with definitely recommend. My only complaint would be the data limit. They would have been much better off Limiting the other features and allowing free use to the main program. you can tell from the other comments too that's been a big catch for a lot of us. The application has extra features like video capture et. Cetra. they would probably sell a lot more if they allowed users to get more familiar with you using the application before running into the roadblocks.

All our apps provide a generous number of free features and usage, ample for amateur investigating or testing the app. Reached the limit? No problem - we have 4 other apps you can try, or return the next day to keep using it for free. For serious investigators, premium is very cheap - less than a cup of coffee.

I only got to try it for a handful of minutes, then it said that I had used up my time today and either upgrade or come back tomorrow. I only use these types of things on occasion, not everyday, so it's not worth it to me if I only get a few minutes of use out of it. Even if I did use it everyday, I still don't think it would be worth it. The "sweep rate" is super slow, full sentences in single sweeps, and most of it sounded like mult other languages. Great idea, poor execution, in my opinion.

I love this app. I've been using it since March of 2022. But the last update ya'll did took away the sensitivity scale. I liked adjusting it depending on where I was using the app. It's a real bummer that it's gone. Also, this app. has said my name multiple times and has also described the color of my shirt, and it has named objects sitting around me that are so random that I don't even notice them until they're mentioned. I wish I could upload my videos to my account profile on GT.

We implemented automatic calibration some time ago making the sensitivity slider obsolete. Cheers for the review.
