Verdict
The clearest difference is rating: Probability Distribution at 4.5 against Preflop Vision's 4.0. Probability Distribution also leads on update cadence (every 2 weeks vs every 2 months) and ratings volume (15 vs 3). Preflop Vision's advantage is in-app purchases (none vs 1) and iOS requirement (12.0 vs 16.0). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Probability Distribution sells 1 one-off in-app purchase. Preflop Vision asks for nothing beyond the download.
Probability Distribution holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Probability Distribution has 15 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 33% of Probability Distribution's written reviews are positive against 38% of Preflop Vision's, so the app with the better star average is not the one people write more warmly about.
Probability Distribution ships an update every 2 weeks, Preflop Vision every 2 months. The most recent releases landed on October 12, 2026 and October 1, 2026 respectively.
