Verdict
The clearest difference is price: CAVES at $4.99 against Model610's $19.99. CAVES also leads on update cadence (every 3 weeks vs every 21 months) and rating (5.0 vs 4.7). Model610's advantage is ratings volume (13 vs 3) and iOS requirement (9.3 vs 17). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
