## What it is
AppSync Unified is a jailbreak tweak (dynamic library) for iOS 5 through 18 that lets users install ad-hoc signed, fakesigned, unsigned, or expired IPA packages that iOS would otherwise reject. It works by hooking into the system's app installation process (installd) to bypass signature validation.

## Use cases
- install unsigned or fakesigned IPA files on a jailbroken iPhone
- install sideloaded apps without re-signing every 7 days without a paid Apple Developer account
- assist iOS app development and testing with Xcode on-device
- clone or downgrade already-installed apps
- install ad-hoc signed or expired app packages

## When to avoid
- your device is not jailbroken
- you need to distribute apps to non-jailbroken devices
- you are unwilling to accept the security and stability risks of system-level tweaks
