Verdict
The clearest difference is price: GeoGebra Graphing Calculator at Free against Probability's $2.29. GeoGebra Graphing Calculator also leads on update cadence (monthly vs every 3 months) and iOS requirement (16.0 vs 26.0). Probability's advantage is review sentiment (97% vs 54%) and rating (4.9 vs 4.3). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
