I think I have this one. I recall paying more than I would have liked to for it.
I just looked it up and on the iPhone.. the title is "Saints" and has an icon of the Theotokos as the desktop icon.
It's good....but, not "that" good.
There are only about 20 biographies listed, and for the icon gallery, it's split by female/male....but, you have no way to "pick" a particular saint. So, to view them you have to scroll through all of them, and truly have no idea if the saint you are looking for will even be there.
Great potential, but, needs some work to be truly useful.
