It's not meant to take the place of the sacrament.
It is instead something that is to be used to better prepare for confession whether you are a practicing or returning Catholic.
From the creator (Of the app -- not that Creator):
Designed to be used in the confessional, this app is the perfect aid for every penitent. With a personalized examination of conscience for each user, password protected profiles, and a step-by-step guide to the sacrament, this app invites Catholics to prayerfully prepare for and participate in the Rite of Penance. Individuals who have been away from the sacrament for some time will find Confession: A Roman Catholic App to be a useful and inviting tool.
I do not mean to belittle Catholicism, or ANY religion, but this seemed a little...umm...weird.
Still, if it makes you a better man or woman -- GO FOR IT!
We need more good people in this world.
