Verdict
The clearest difference is price: GeoGebra 3D Calculator at Free against Probability's $1.99. GeoGebra 3D Calculator also leads on update cadence (monthly vs every 3 months) and iOS requirement (16.0 vs 26.0). Probability's advantage is rating (4.9 vs 4.0) and review sentiment (97% vs 66%). On ads, in-app purchases, monetization model and device support there is nothing between them.
