# PDF vs Vellum Schedule

The clearest difference is in-app purchases: Vellum Schedule at none against PDF's 1. On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. PDF sells 1 one-off in-app purchase. Vellum Schedule asks for nothing beyond the download.
