A complete file manager that includes robust unzipping capabilities.

ZArchiver is indeed available on Apple’s App Store, with multiple versions currently offered by different developers. One of the most visible official versions is published by TIMON SOFTWARE CO., LTD, and it supports iOS 14.0 or later. Another version, titled “ZArchiver - Zip UnZip,” appears under a different publisher and requires iOS 12.0 or later. There is also a version called “ZArchiver - Extract Zip File” that works with iOS 13.0 and above.

ZArchiver was built by its developers specifically for the Android operating system to interact with Android's open file system. Because iOS handles file management and app sandboxing entirely differently, porting ZArchiver directly is not a straightforward task. Beware of Fake ZArchiver IPA Downloads

An (iOS App Store Package) is the archive format used to distribute iOS apps. It contains the compiled code, assets, and metadata needed to install an application on Apple devices. For most users, apps are obtained directly from the App Store; however, in some cases—particularly for apps that are not globally available, for developers testing their own applications, or for sideloading third-party tools—IPA files become the preferred distribution method.

Locate a ZArchiver IPA from a trusted source, preferably one with user reviews and regular updates. (Approach third-party sites with caution.)
