Because Android is an open source system, and Apple is a closed source system.

IOS is a mobile operating system developed by Apple. Apple announced this system for the first time at Macworld conference on June 9, 2007. It was originally designed for iPhone, and later applied to iPod touch and iPad. IOS, like apple's macOS, belongs to a commercial operating system similar to Unix.

Originally this system was called iPhone OS. Because iPad, iPhone and iPod touch all use iPhone OS, it was announced on 2065 438+00 WWDC that it was renamed as iOS(iOS is the registered trademark of Cisco's network equipment operating system in the United States, and Apple's renaming has been authorized by Cisco).

Starting from the iOS 1.0 version, enterprise-level third-party software can run on the iPhone. However, these softwares are facing the situation of being completely destroyed by any iOS update, although Apple has stated that it will not specifically design a system upgrade to destroy these third-party softwares.

These third-party software are distributed through the Apple Developer Enterprise Program? This is a development method for enterprise management that Apple officially released to entrepreneurs. These apps won't appear in the App Store? .
