As I found out later, after an e-mail response to my questions, when you go to save the image you needed to tab on the ADVANCED EXPORT tab to access the menu for high resolution and a 2x3 format image. When you tab on the ADVANCED EXPORT tab another screen appears and you will need to turn off the "Square Crop" button and then tab on the Save to Camera Roll to get the high resolution image into your camera roll. Even if you opened the app with the square crop, when you turn it off before saving, it will deliver the original formatted image.
I like to layer several images when processing and I think this will be a great App to work with in layering. Here are a few more out of the App images...no layers no processing just App results which are fun.
Right now in the app you can adjust, brightness~darkness, line strength and select from several FX. You can also buy in app another set of FX. I would like one more contol and that would be a color picker to adjust the color of the rendered effect. This is not a complete assortment of what the app can do but will give you an idea.
And here is the original shot.
