You cannot record you cannot take a photo you cannot choose a different color from with in this app.

The only way to use it is to put it behind your head use a separate device and then record. He is not telling you what this app is....

So what he has done is help you not to go to the fabric store to buy a green screen. The problem with this is is he is not explaining anything. Clearly so that the buyer knows what they are receiving. Go to the fabric store buy green fabric put it behind your head.

ITS NOT SCAM! Please read description before buy! At first! This app made for professional cinema/video industry. It made to shot on video camera scene with iPhone in hand(for example) and track and replace screen with desirable screen capture. It’s very useful tool because it have brightness level controll for right exposition, and can change chroma to green blue and white. Again it’s not a “scam” as you say. Please make request for refund, I no need your money. Apple clearly explain how to do that https://support.apple.com/en-us/HT204084

It just turns your iPad/ iPhone screen green, but does nothing beyond that. That’s why even the developer doesn’t have instructions on how to use it and does not intend or bother to explain how to use it. Buy at your own risk!!!!

It’s not scam! Yes it just color! Chroma key color, and brightness control. It very useful tool for video industry. I originally made this app for my needs in video business. If you don’t know how to use please don’t download, It simple rule. People who need this tool never ask questions like this. And read description before download.
And don’t rate one star if you just don’t know how to use it if you never use it as intended!
All the best!
