iPadOS 16 is rated to make Apple's flagship tablets more powerful Pro devices
Apple has introduced what might be one of the most cross-device new versions of iPadOS for some time. Many of the new features included in the upcoming major upgrade are also intended to work on iPhones or Macs, the new Home app with Matter support, new, more "fluid" dictation modes and iCloud shared photo libraries for families included.
On the other hand, iPadOS 16 does have its own APIs for the new and expanded suite of online team-oriented tools that work across FaceTime and other apps. On that note, Apple's new Collaboration feature, by which multiple users can work on, amend and add to a kind of communal online whiteboard in real time, may be particularly suited to the iPad Pro thanks to its Pencil support.
Similarly, iPadOS 16 might be a good fit for Apple's new Stage Manager window-management mode, as well as the new Reference mode to match display colors across devices. It also finally introduces a tablet-optimized Weather app, as well as the new Passkey password alternative option in Safari. It is available either as a developer beta from now, or later in 2022 as a stable upgrade.
