Verdict

The call

The clearest difference is rating: Contixo at 5.0 against LightPDF's 4.1. Contixo also leads on update cadence (every 3 days vs every 2 weeks) and review sentiment (100% vs 88%). LightPDF's advantage is ratings volume (54 vs 3) and iOS requirement (14.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.
