What is app sideload and can Apple sideload apps like Android

Sideloading of apps is mostly a Android thing, IOS is a closed system that does not have this capability

[nicklisac]

There are developers who have poured heart & soul into their apps only to have them removed from the play store and forced to start all over again with very little or no explanation from an uncompromisin Google.
It doesn't seem to be a level playing field for developers.

I can see both sides of the argument for why Apple shouldn’t be forced to allow sideloading apps on iOS/iPadOS.

Whatever I need is in the Apple store. Very good explanation

Samsung has the Samsung Galaxy store on its phone. There is also the Amazon app store

I don’t need sideloading, the App Store has everything I need
