Verdict
The clearest difference is in-app purchases: Libraryai at none against BookSlayer's 8. Libraryai also leads on ads (none vs shown). BookSlayer's advantage is update cadence (fortnightly vs every 2 months) and iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.
