Developers have separated the version of the operating system for tablets from the usual iOS and gave it a new name, because it has become something between a mobile operating system and a computer: it can still run only ARM-applications, but a lot of new gestures and features make its interface and interaction with it a kind of simplified macOS (platform for Macs).
The new version of the operating system (perhaps, it is impossible to call it a separate platform) is available to all tablets running on the Apple A8 processor and newer:
iPad Pro (12.9 inches).
iPad Pro (11 inch).
iPad Pro (10.5 inch).
iPad Pro (9.7 inches).
iPad (7th generation-2019).
iPad (6th generation-2018).
iPad (5th generation-2017).
iPad mini (5th generation-2019).
iPad mini 4.
iPad Air (3rd generation — 2019).
the iPad Air 2.
With the release of iPadOS on tablets, earned a new gaming service from Apple, which opens access to games without ads, microtransactions and mandatory Internet connection. All games in it are multiplatform (within the "Apple" ecosystem), so you can start the passage on one device, and then continue from the same place on the other (synchronization occurs through cloud storage).
