What is AppSync Unified?

AppSync Unified is a powerful tweak designed for jailbroken iOS devices. It allows users to install unsigned IPA files (apps) on their iPhones or iPads.

By default, iOS only permits apps signed with Apple’s official developer certificates, which restricts the installation of modified, outdated, or custom apps. AppSync Unified bypasses these restrictions, enabling you to sideload any app you want.
