# Online Knowledge Universe vs Automotive Engineering

The clearest difference is iOS requirement: Online Knowledge Universe at 12.4 against Automotive Engineering's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Online Knowledge Universe sells 3 one-off in-app purchases and Automotive Engineering sells 6 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
