Exodus International is that gross group that runs camps and workshops to "cure" people of their gayness—I never used the app, but it looks like it as mostly used to gets news and event updates from Exodus. Apple originally gave the Exodus app a 4+ rating from Apple, meaning that it contains "no objectionable content."
Hilariously, a counter-petition went up to demand Apple keep the app and fight "reverse suppression from gays." So far, it only has ten signatures.
