Green Screen Studio is a chroma key application that allows the user to change a monochromatic background into any image they wish. Chroma key is a technique for mixing two images or frames together, in which a color from one image is removed (or made transparent), revealing another image behind it. This technique is also referred to as color keying, color-separation overlay, greenscreen, and bluescreen.

Green Screen Studio has tools available to manually remove the background if you do not have a perfect greenscreen background available. This allows you to manually apply backgrounds to any picture you want without a greenscreen.

✓ Apply backgrounds automatically
✓ Apply backgrounds manually using a selection of tools without having a green screen
✓ Fully functional photo editing tools!
✓ Intelligent one-tap Auto Enhance filter.
✓ Draw on your photos.
✓ Add fun stickers and text.
✓ Adjust Brightness, Saturation and Contrast.
✓ Sharpen and Blur.
✓ Adjust, Crop, and Rotate your photos.
✓ Red-Eye, Whiten and Blemish tools
✓ Additional ten gorgeous photo effects to apply to your photos.


Green is currently used as a backdrop more than any other color because image sensors in digital video cameras are most sensitive to green. The green camera channel contains the least "noise" and can produce the cleanest key/matte/mask. Additionally, less light is needed to illuminate green, again because of the higher sensitivity to green in image sensors.

The biggest challenge when setting up a greenscreen is even lighting and the avoidance of shadow, because it is best to have as narrow a color range as possible being replaced. A shadow would present itself as a darker color to the camera and might not register for replacement.

A chroma key subject must not wear clothing similar in color to the chroma key color(s) (unless intentional), because the clothing may be replaced with the background.

To avoid memory related crashes that are common in all image processing apps, perform a hard reset by holding the top button on your device for 2 seconds.

Not sure what happened!?

This app used to be fun... It is now constantly crashing and it's becoming a serious trigger for my brain to close all protein gates for all endorphin re-uptake. Because of this incessant crashing (physical and literal), I am now addicted to anti-depressants and need counseling. PLEASE FIX THIS! We all know that Obamacare won't cover my psychiatry bills... Pleeeeeeease... Don't you see how your app errors are significantly impacting our nation's need for non-socialized medicine?! Ohh.. Wait. Don't fix it!!!


I do not understand why Apple would permit such fraud in their App Store. It is wildly apparent that this app DOES NOT WORK!!! I guess I was naive to think that it was as bad as everyone said and would still be available. And the "help" offered on the developers web site is meaningless. Telling us to reboot is not support. Apple should do a better job of policing its developers and banning them from stealing again from Apple customers. Only giving 1 star to enable the submission.

Sorry! Had to change review!

I was a firm advocate of this app! However with recent updates, the app is no longer functional. Usually you can contact the developer through the app to attempt to resolve issues, but since it crashes upon opening that's not an option. No other links to contact. Once crash problem is fixed and I am able to once again use what I paid for, I'll re-up my rating.
