# Learn CSS vs PrepLockin

The clearest difference is in-app purchases: PrepLockin at none against Learn CSS's 1. Learn CSS's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price and ads there is nothing between them.

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