Both Apple and Google police their app stores for bullying and hate speech, but every now and then we can only assume something must slip through the net of reviewers and content moderators. That's about the only reason we can see for an app like Setting Captives Free ever seeing the light of day.
The app is a supposed cure for gambling, smoking, and sexual impurities - such as homosexuality. The app 'educates' those trapped in the "bondage of homosexuality" that they are not "born this way", and that they can be cured by simply following the various 60-day courses the app offers.
This would certainly seem to fly in the face of Google's Developer Program Policies:
Hate Speech: We don't allow the promotion of hatred toward groups of people based on their race or ethnic origin, religion, disability, gender, age, veteran status, or sexual orientation/gender identity.
A petition on allout.org, calling for the app's removal, has already received over 40,000 sigantures, and Apple has removed the app from it's store. Google's not caught up yet, however.
Many psychiatric and health organisations consider gay cures to be actively harmful to LGBTI individuals.
