What Is ShadowBlock?

ShadowBlock is a technical network utility for iOS that provides deep traffic inspection, HTTPS decryption, and rule-based content blocking. Aimed at power users and network admins, it offers advanced features like URL rewriting and local DNS mapping for a low one-time fee of $1.99. However, the app has not been updated since 2019 and holds a poor 1.8-star rating, suggesting it is no longer a viable competitor against modern, actively developed tools like Quantumult X.
