Keynote for iOS has always been designed around interaction more than its macOS counterpart, partly because it’s more likely you’ll be using a single screen to present than multiple monitors. That shows clearly in this minor update. And many of the new features bring Keynote for iOS into feature parity with its macOS counterpart, as well as a consistent interface and set of options alongside Pages and Numbers on both platforms.
Keynote for iOS: Apple Pencil support
Just as you can in the other iWork iOS apps (Pages and Numbers), Apple Pencil or your finger can be used to create drawings on iPads with Pencil support. This a useful improvement for Keynote—making as much sense here as in Pages—with the added benefit that Keynote for iOS can animate the drawings you create by effectively replaying them.
