What about something like F-Droid? F-Droid users can even add new repos to source apps from if you don't want to submit it to wherever F-Droid sources from by default.

That said, the culture around smartphones unfortunately was poisoned from the beginning so that normal users are suspicious of anything that doesn't come from the "official" corporate app stores, unlike PCs where they'll download just about anything on the internet, so I do sympathize with swearing off app development.
