# Quick Brain vs The Dojo

The clearest difference is iOS requirement: Quick Brain at 15.5 against The Dojo's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Quick Brain sells 10 one-off in-app purchases and The Dojo sells 2 in-app purchases, starting at $11.99 per month. Whichever you choose, the download price is not the number that matters.
