# Pre vs CV

The clearest difference is in-app purchases: Pre at none against CV's 1. Pre also leads on iOS requirement (13.0 vs 17.6). On price, ads and device support there is nothing between them.

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