Before exploring the available methods, it is important to understand why Android apps do not normally work on iPhones.
Android applications are typically distributed through the Google Play Store and may also be available as APK files. These applications are designed to operate within Android's software environment, using Android-specific system services, application programming interfaces, and runtime components.
iPhones use Apple's iOS operating system, which has its own application framework, security restrictions, and installation requirements. As a result, an Android APK file cannot simply be downloaded and installed on an iPhone.
