Works well but two major limitations

The app works as well as any Ive found on the App Store but it has two major limitation. First, as noted, it only works with a green background. If your model is wearing any green, this is a issue. There is no ability to designate the background color like a blue background. Second is the output is limited to 1400 pixels maximum dimension. This makes the app only useful for creating online images.
