# Probability vs Probability

The clearest difference is in-app purchases: Probability at none against Probability's 1. Probability also leads on iOS requirement (9.0 vs 14.0). Probability's advantage is update cadence (every 10 days vs every 18 months). On price, ads and device support there is nothing between them.

Both are free to download. Probability sells 1 one-off in-app purchase. Probability asks for nothing beyond the download.

Probability ships an update every 18 months, Probability every 10 days. The most recent releases landed on October 6, 2026 and October 5, 2026 respectively.
