# CND Security Exam Prep 2026 vs SQL Hero

The clearest difference is ads: CND Security Exam Prep 2026 at none against SQL Hero's shown. SQL Hero's advantage is iOS requirement (13.0 vs 15.1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. CND Security Exam Prep 2026 sells 6 in-app purchases, starting at $5.99 per 7 days and SQL Hero sells 10 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
