From android cannot get apple app from Google play store

What "apple app"? Apple itself doesn't make too many apps for the Android platform. The Music app is available through the Google Play store.

If you have a third-party app on your iPhone that you want on an Android phone, you'll need to check to see if the developer makes a version available in the Google Play store.

I have no idea what you're on about. Amazon has not discontinued the Kindle app for iOS. I've used it continuously since it was released.

Your issue has nothing to do with Google or Amazon or Apple. It has to do with whoever developed the game you're concerned about. They have the ability to create a version for both platforms and provide a way to transfer the data. If they have chosen not to do that, that's on them. They may not have an interest in or the knowledge in programming for the other platform

Try to get the kindle app to stay in sight in your apps in your ios iphone. You can't without it being being hidden by apple. Same problem across the board. Lack of cooperation between the corporations

It's been on my home screen for years. I have no problem keeping it there. Perhaps you don't understand something about how the App Library works or the way the recent Focus updates can affect the Home screen.

I also have no trouble keeping apps from Google on my home screen.

You may. If the developer of the app makes a version available on the Android platform and they offer a way to transfer your data, you may not. Contact the developer.
