Apple’s Freeform collaboration tool, due out “later this year,” is designed to give remote teams a limitless virtual whiteboard within which they can work together.
We don’t know much about it beyond what was announced at WWDC 2022, but we do know not to expect it to appear in the first iterations of the Mac, iPad, and iPhone operating systems when they ship in fall. (Given recent claims the release of iPad OS 16 has been delayed pending changes in Stage Manager, it seems reasonable to think Freeform may also be delayed.)
