I got the app on sale a while back but really haven’t used it much. However, it really does make creating nice-looking images easy. They have a lot of cool backgrounds, and you can type in your quotation and alter the color scheme.
Warning: If you’re used to Photoshop, it will probably get frustrating for you not to have much control over sizing and spacing of individual words.
P.S. If you don’t know much about Padre Pio, google him. He is an amazing Saint with all kinds of miraculous specials! <3
