Apple has removed an app from the “ex-gay” group Exodus International from its iTunes store.

The company removed the app on Tuesday after nearly 150,000 people signed onto an online petition sponsored by Truth Wins Out, a group founded specifically to counter the claims of “ex-gay” ministries.

“It's official, the @ExodusInl App is no longer in the @AppStore,” Exodus International President Alan Chambers tweeted late Tuesday to his nearly 700 followers. “Incredibly disappointing. Watch out, it could happen to you. #freedom.”

A search on iTunes verified the app was no longer available in the digital store.

Wayne Besen, president of Truth Wins Out, earlier said he was petitioning for the app's removal because Exodus' message is harmful.

“Exodus' message is hateful and bigoted,” Besen wrote on his group's website. “They claim to offer 'freedom from homosexuality through the power of Jesus Christ' and use scare tactics, misinformation, stereotypes and distortions of LGBT life to recruit clients. They endorse the use of so-called 'reparative therapy' to 'change' the sexual orientation of their clients, despite the fact that this form of 'therapy' has been rejected by every major professional medical organization.”

“But reparative therapy isn't just bad medicine – it's also very damaging to the self-esteem and mental health of its victims.”

Besen also claims the app specifically targets vulnerable gay youth.

“In light of the recent wave of LGBT youth suicides, this tactic is particularly galling as it creates, legitimizes, and fuels the ostracism of LGBT youth by their families.” (A Truth Wins Out video urging Apple to dump the “ex-gay” app is embedded in the right panel of this page.)

Last year, Apple removed an anti-gay app after thousands signed onto a similar online petition.
