# 凱利計算機 vs Probability

The clearest difference is in-app purchases: 凱利計算機 at none against Probability's 1. 凱利計算機 also leads on iOS requirement (11.0 vs 14.0). Probability's advantage is ads (none vs shown). On price, review sentiment and device support there is nothing between them.

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