Verdict

The call

The clearest difference is monetization model: Book Cast Player at free against Undulib's paid. Book Cast Player also leads on rating (5.0 vs 4.5). Undulib's advantage is ratings volume (29 vs 2) and iOS requirement (9.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
