# Brain vs AWS SOA

The clearest difference is ads: Brain at none against AWS SOA's shown. Brain also leads on iOS requirement (15.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
