— once the standard tool for sideloading — uses your Apple ID to generate a developer certificate, signs the IPA with that certificate, and installs it onto your device. However, Cydia Impactor has faced increasing stability issues on modern operating systems. Sideloadly has emerged as a more reliable alternative that supports both USB and Wi-Fi connections.

IPA apps on iOS 9.3.5 offer users a way to access a wider range of applications, including those no longer available on the App Store or restricted to specific regions. However, the use of IPA apps comes with risks, including security vulnerabilities and stability issues. Users should exercise caution when installing IPA files and only download from trusted sources.

Install apps that require iOS 10+ or newer.

Rename the resulting file from Archive.zip back to YourAppName.ipa .

There are several reasons why an app might need to be patched before it can be installed on iOS 9.3.5:

presents a unique set of challenges for users. Primarily, this operating system was the last update for several legacy 32-bit devices, including the iPhone 4s, iPhone 5, iPad 2, and iPod touch 5th generation. Because of its age, many apps from the App Store either have dropped support for iOS 9 or are no longer receiving security updates. This is where the concept of a "patched IPA" comes into play.

With Apple pushing new software updates every year, devices running older operating systems are often rendered obsolete. The iPhone 4S, iPad 2, iPad 3, and the original iPad Mini are prime examples, largely stuck on iOS 9.3.5 or iOS 9.3.6. While the official App Store has abandoned these devices, it is still possible to use them effectively.
