# PSM 1 Scrum Master Exam Prep vs CertPrep

The clearest difference is iOS requirement: PSM 1 Scrum Master Exam Prep at 15.1 against CertPrep's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PSM 1 Scrum Master Exam Prep sells 9 in-app purchases, starting at $8.99 per 7 days and CertPrep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
