Verdict

The call

The clearest difference is review sentiment: JOJO Math and Reading at 96% against Cretapedia's 44%. JOJO Math and Reading also leads on rating (4.9 vs 4.6) and update cadence (every 9 days vs monthly). Cretapedia's advantage is ratings volume (1.7K vs 41) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.
