Cydia Impactor was once a popular tool for installing apps on iOS devices outside of the App Store. However, Apple’s increasing security measures have made it more difficult to use Cydia Impactor, and updates to iOS have rendered the tool incompatible in some cases. Additionally, the developer certificate used by Cydia Impactor to sign IPA files has been revoked by Apple, which means that it may no longer work with certain apps.
Furthermore, Saurik, the developer of Cydia Impactor, has announced that he will no longer be actively developing or maintaining the tool due to personal reasons. As a result, there have been no updates or fixes to address the compatibility issues that have arisen with newer versions of iOS.
Users looking to install apps outside of the App Store can consider using alternative tools such as AltStore or Sideloadly, which use a different approach to installing apps on iOS devices. AltStore uses a self-signed certificate to bypass Apple’s security measures, while Sideloadly utilizes a developer account to sign the IPA files. These tools may offer a more reliable and user-friendly experience for installing apps on iOS devices compared to Cydia Impactor.
