AppSync Unified

Install any IPA file to iOS 5 - 16 jailbroken devices

Introduction to AppSync Unified

Unified AppSync dynamic library for iOS 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16.

AppSync Unified is a jailbreak plugin that allows users to freely install temporarily signed, falsely signed, or unsigned IPA application packages on their iOS devices that would otherwise be considered invalid by iOS.

Some popular use cases include:

  • Install freely distributed apps that are not available in the App Store without having to re-sign up for them every 7 days (if the user is not subscribed to the Apple Developer Program).
  • Assist in developing iOS applications using Xcode
  • Cloning or downgrading installed applications

Do not use AppSync Unified for piracy.

AppSync Unified is a development tool designed first and foremost for application developers, in addition to other valid and legitimate uses that I support (some of which are outlined above).

Software piracy is illegal.Please support the developers of the iOS software you use, whether they are developers of apps on the App Store or developers of plug-ins for jailbreak repositories.

They're just trying to make a living, just like you and me.
