# StatsSims vs Probability Distribution

The clearest difference is in-app purchases: StatsSims at none against Probability Distribution's 1. StatsSims also leads on review sentiment (50% vs 33%) and iOS requirement (6.0 vs 16.0). Probability Distribution's advantage is rating (4.5 vs 4.2) and update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Probability Distribution holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 5 and 15 respectively. Written reviews complicate that: 50% of StatsSims's written reviews are positive against 33% of Probability Distribution's, so the app with the better star average is not the one people write more warmly about.

StatsSims ships an update every 2 months, Probability Distribution every 2 weeks. The most recent releases landed on June 11, 2026 and September 9, 2026 respectively.
