Verdict
The clearest difference is price: Prusa at Free against Circuit Playground's $2.99. Prusa also leads on ratings volume (117 vs 19). Circuit Playground's advantage is review sentiment (86% vs 50%) and rating (4.3 vs 4.0). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
