## Description

FLEX is an in-app debugging tool and runtime exploration environment for iOS applications. It provides an integrated suite for inspecting and modifying the internal state of a running process without the use of an external debugger.

The project includes a runtime inspector for browsing the memory heap and calling methods dynamically, alongside a view hierarchy debugger for visualizing and adjusting layout structures in real time. It features a network traffic monitor to log and analyze HTTP request history, headers, and responses, as well as a sandbox manager for viewing and editing files and databases stored on the local device.

The toolset covers broader capabilities for memory analysis, state modification of live objects, and system log viewing. It also includes utilities for managing user defaults and simulating touch pressure for haptic interaction testing.
