The real iCleaner is a , not an IPA. It is designed to be installed via Cydia, Sileo, or Zebra on a jailbroken device. The app hooks deep into iOS system frameworks (using MobileSubstrate or libhooker ) to delete cache files that normal apps cannot access. Because of this, a standard IPA cannot replicate the full functionality of iCleaner.
With modern jailbreaks (like Dopamine) and techniques like MacDirtyCow/KFD, file system access is maintained, and iCleaner Pro is updated to support newer iOS versions. What is the difference between iCleaner and iCleaner Pro?
There is a recent gray area. With the discovery of the CVE-2022-26766 vulnerability (TrollStore), users can permanently sideload IPAs without a full jailbreak. Some developers have attempted to port a limited version of iCleaner to IPA format for TrollStore.
