# Preg Wheel vs ACOG

The clearest difference is rating: ACOG at 4.9 against Preg Wheel's 4.0. ACOG also leads on review sentiment (90% vs 59%) and ratings volume (6.3K vs 62). Preg Wheel's advantage is iOS requirement (10.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
