There is no official way to install Google Play apps on an iPhone. However, there are a few workarounds that allow you to install and use Android apps on your iPhone.
One method is to use a web-based app store such as Appetize.io. This service allows you to run Android apps in your web browser.
Another method is to use a third-party app store such as Cydia Impactor. This software allows you to sideload Android apps onto your iPhone.
Finally, you can use an emulator such as the Android SDK to run Android apps on your computer.
