# Dynamics MB vs CertPrep

The clearest difference is device support: Dynamics MB at 4 against CertPrep's 2. Dynamics MB also leads on iOS requirement (13.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Dynamics MB sells 1 one-off in-app purchase and CertPrep sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
