# Probability vs 123法律

The clearest difference is in-app purchases: 123法律 at none against Probability's 1. 123法律 also leads on iOS requirement (12.0 vs 14.0). Probability's advantage is device support. On price there is nothing between them.

Both are free to download. Probability sells 1 one-off in-app purchase. 123法律 asks for nothing beyond the download.
