Verdict

The call

The clearest difference is in-app purchases: Antilibrary at none against BookPlayer's 15. Antilibrary also leads on review sentiment (100% vs 83%) and iOS requirement (17.0 vs 26.0). BookPlayer's advantage is ratings volume (20K vs 4) and chart position (#50 vs unranked). On price, rating, update cadence and ads there is nothing between them.
