Verdict

The call

The clearest difference is rating: Persian Dictionary at 4.8 against Fastdic's 4.5. Persian Dictionary also leads on ratings volume (86K vs 11K) and review sentiment (87% vs 76%). Fastdic's advantage is update cadence (every 5 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
