Well, the organisation that created this app explicitly believes that. There's nothing implicit about it.

But it's not like they're forcing this app on people. I'm assuming it's being willingly used by people who believe homosexuality is wrong and think they can stop their own homosexual urges.

If that's what they believe, let them go for it, I reckon. I don't have a right to tell them that they should be having relations that they clearly believe are wrong or immoral.
