Access to Unavailable Apps: Some apps may not meet App Store policies or are region-locked, making them accessible only through IPA installation.
Customization and Tweaks: Many third-party apps offer unique features not found in their App Store versions.
Enterprise Applications: Businesses often use IPA files to distribute custom apps to employees.
Beta Testing: Developers distribute IPA files for testing before releasing them on the App Store.
