# Custom PDF vs RubiMask

The clearest difference is iOS requirement: Custom PDF at 12.0 against RubiMask's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Custom PDF sells 1 in-app purchase, starting at $1.00 per month and RubiMask sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
