# ISC2 Official Exam Prep vs CertPrep

The clearest difference is device support: ISC2 Official Exam Prep at 4 against CertPrep's 2. ISC2 Official Exam Prep also leads on iOS requirement (15.6 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. ISC2 Official Exam Prep sells 5 in-app purchases, starting at $5.99 per 7 days and CertPrep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
