Devout iPhone and iPad users with a guilty conscience can now download a confession app to help them confess their sins.

The new app, called “Confession: A Roman Catholic App,” has even been approved by some American Catholic priests. It calculates the users sex, age and occupation, and how much time has passed since the person’s last confession. The apps “examination of conscience”  then decides what penance to impose.

Developed by Little iApps, a three-man company based in Indianapolis, the company describes its invention as “a step-by-step guide to the sacrament, inviting Catholics to prayerfully prepare for and participate in the Rite of Penance.”

Little iApps' Patrick Leinen told the “Daily Mail”, “Our bishop was very excited about it.

''We were able to work with several priests in order to get that examination of conscience created, so it was kind of fun.

“When we were actually testing out the software before release we had one gentleman who hadn't been to confession in about 20 years.

“He did his confession with it and he said it made it much easier on him,” he added.
