Verdict
The clearest difference is ads: Postersz at none against Cavline's shown. Postersz also leads on update cadence (every 3 days vs every 5 weeks) and monetization model (free vs ad-supported). Cavline's advantage is ratings volume (10 vs 1). On price, rating, in-app purchases and device support there is nothing between them.
