"Confession: A Roman Catholic App", created by a US-based company called Little iApps, is designed for Apple devices such as iPhone, iPad and iPod, the Telegraph reported.
The application costs $1.99 in Apple's iTunes store.
It offers password protected customised profiles, a guide to performing the sacrament as well as a list of acts of contrition.
"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," its developer, Patrick Leinen, was quoted as saying.
He said the application has received the imprimatur from Bishop Kevin Rhoades of the Fort Wayne- Indian-based diocese, the first programme to receive the stamp of the church.
