## What it is
FishChat is an Objective-C hooking project that injects a dylib into a decrypted WeChat.app binary to modify its behavior on non-jailbroken iOS devices. It enables tweaks like disabling Discover-page entries, faking step counts, removing red badges, night mode, and preventing message recalls via code-signing repackaging.

## Use cases
- customize WeChat features without jailbreaking
- prevent message recall in WeChat
- fake WeChat step count
- enable WeChat night mode
- hide Moments and Discover page entries
- learn iOS dylib injection and repackaging techniques

## When to choose
- you want to modify a decrypted WeChat IPA on a non-jailbroken iPhone
- you are studying iOS reverse engineering and dylib injection workflows

## When to avoid
- you need a maintained tool for current WeChat versions
- you require a jailbroken tweak environment
- you need a permissively licensed project

## Facets
- artifact type: library
- maturity: abandoned
- function: reverse-engineering, security
