# IT Knowledge vs CertPrep

The clearest difference is iOS requirement: IT Knowledge at 15.0 against CertPrep's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. IT Knowledge sells 2 one-off in-app purchases and CertPrep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
