# Probability Distribution vs Probability Lab

The clearest difference is iOS requirement: Probability Distribution at 16.0 against Probability Lab's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Probability Distribution sells 1 one-off in-app purchase and Probability Lab sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
