# AZ vs CertPrep

The clearest difference is iOS requirement: AZ at 13.4 against CertPrep's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. AZ sells 2 in-app purchases, starting at $8.99 per 7 days and CertPrep sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
