That’s a very polite way to say “it’s broken”.
I downloaded Bookshelves, imported two books, and the next time I opened the app it greeted me with “Book Not Available” errors for both of the books. Apparently the backend database (along with the app) is vibe-coded—there are numerous signs—and could become corrupted at short notice.
Lora but no Georgia font is a horrific crime. The reading UI is ugly, a cheap imitation of Apple Books.
The ad post says no telemetry but the in-app “Disable Analytics” option is off by default.
I would never recommend a new, vibe-coded app to anyone. Especially one advertised aggressively on r/MacApps. It’s a guaranteed disappointment. Totally vibe-coded apps don’t age well. They peak at the moment you know of it.
