# BookBase vs Cortex Atlas

The clearest difference is iOS requirement: Cortex Atlas at 13.0 against BookBase's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BookBase sells 10 in-app purchases, starting at $9.99 per month and Cortex Atlas sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
