"Confession: A Roman Catholic App" does not purport to take the place of an actual confession. Not even the Catholic Church, tech-savvy as it is with the Vatican tweeting in six languages, would approve that. Rather, it guides you through the Ten Commandments with a slew of questions attached to each.
Check boxes for the sins you've committed -- and there are many, as any lapsed Catholic knows. The $1.99 app then guides you through contrition and an exchange with a real-life priest, who can then absolve you of your sins.
