I was raised protestant, but not presbyterian. Still, I haven’t heard a lot of excommunication coming from any protestant group. That is mostly a Catholic thing I think, with some of that happening with maybe Puritans (I’m not that familiar with all of them) back around Salem Witch Trial days.
I once made an app for Samsung watches for disc golf scorekeeping. It could accept any number of players, apply a handicap throughout the game so you could know exactly how you were doing vs your opponent with different handicaps on every hole, and gave a nice scorecard at the end to view. It was $0.99
Someone complained that I made them “throw away their money down the drain” since it didn’t also have gps to tell them how far they were from the hole.
