# ADM vs CertPrep

The clearest difference is iOS requirement: ADM at 13.0 against CertPrep's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ADM sells 4 in-app purchases, starting at $7.99 per month and CertPrep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
