I think a good exercise would be to describe the apps and such on your phone that each of us use to assist in our lives as a Catholic; this will give us an idea of what can be moved into this SaintMaker app from the beginning so as to replace what we currently use.
For me, it's mostly a series of google docs that hold examinations of conscience, daily prayers, records of adjustments I need to make to improve my life (removing vices, adding virtues, etc), and the like. I also have a few note widgets, acting as checklists, that help keep me on track to say morning/nightly prayer and the examination of conscience. I can’t think of many social/community apps that I would use other than say maybe a Catholic forum (which I would access through a website normally).
