Campaigners have thanked Apple for removing an app from its store that they said stigmatised LGBT people.
The software promoted a US religious group that says homosexual practice is sinful and that its members should help “call up” others to their natural-born “biblical gender”.
Apple’s store now says the app is not available, but the tech firm has not commented on the matter.
Google and Amazon continue to offer Android versions of the app.
The Christian organisation involved, Living Hope Ministries, has told NBC News that it plans to challenge Apple’s action.
The Arlington, Texas-based body is not related to a UK-based church that goes by the same name.
Apple’s rules state that apps should not include content that is “defamatory, discriminatory, or mean-spirited” including commentary about sexual orientation.
