# JamEngine vs Scale Syllabus

The clearest difference is device support: Scale Syllabus at 4 against JamEngine's 2. Scale Syllabus also leads on iOS requirement (15.0 vs 18.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. JamEngine sells 1 one-off in-app purchase and Scale Syllabus sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
