Listed on a website dedicated to the app, which is set to be launched in early 2017, the benefits to users include finding their nearest Holy Mass and Confession at the tap of a button.
Parishes are all plotted on an interactive map and users are even given weekly spiritual inspirations delivered directly to their phone or tablet.
The app also claims to be of benefit to dioceses by increasing the number of Catholics attending churches.
Developers say it will help younger Catholics - particularly in the age group 18 to 55 - to be more engaged in dioceses, as they most utilise smartphones and tablets as well as saving on printing costs.
Among the weekly inspiration quotes is: 'Only when we meet the living God in Christ do we know what life is.'
