# Library vs Folio

The clearest difference is in-app purchases: Library at none against Folio's 1. Library also leads on iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.

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