# Schema vs Aevum

The clearest difference is iOS requirement: Aevum at 13.0 against Schema's 18.0. On price and in-app purchases there is nothing between them.

Both are free to download. Schema sells 2 in-app purchases, starting at $14.99 per month and Aevum sells 9 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
