# O'Reilly vs AWS Certification Exam Prep

The clearest difference is ads: O'Reilly at none against AWS Certification Exam Prep's shown. AWS Certification Exam Prep's advantage is iOS requirement (16.4 vs 18.5). 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.
