: Historically, jailbreaking an iOS device was a prerequisite for installing IPA files not sourced from the App Store. However, with the evolution of technology, methods to install IPA files on non-jailbroken devices have emerged.

Cracked apps are software applications that have been altered or "cracked" to bypass their original licensing or payment requirements. These modifications allow users to download and use the app for free, circumventing the need for a purchase or subscription. Cracked apps can include everything from games and productivity tools to professional software and operating systems.

: Tools like Cydia Impactor, AltStore, and others allow users to install IPA files on their devices without jailbreaking. These tools often require a computer and a USB connection to the device.

: After installation, users may need to trust the app in their device's settings to ensure it can run without restrictions.
