AppSync Unified, written by Karen/あけみ is a tweak that allows users to freely install ad-hoc signed, fakesigned, or unsigned IPA app packages on their iOS devices that iOS would otherwise consider invalid.
Some popular use cases include:
- Installing freely-distributed apps that are unavailable from the App Store without having to re-sign the apps in question every 7 days (if the user does not have a subscription to the Apple Developer Program) - Assisting in the development of iOS applications with Xcode - Cloning or downgrading already-installed apps
It can be downloaded from https://cydia.akemi.ai/
