CUPERTINO, Calif.—After going into detail about iOS 18, Apple took a few moments in its WWDC 2024 keynote to walk through changes

There are a few minor UI changes and new features across Apple's first party apps. That includes a new floating tab bar. The bar expands into the side bar when you want to dig in, and you can customize the tab bar to include the specific things you want to interact with the most. Additionally, SharePlay allows easier screen sharing and remote control of another person's iPad.

But the big news is that the Calculator app we've all used on the iPhone to the iPad, after years of the iPad having no first-party calculator app at all. The iPad Calculator app can do some things the iPhone version can't do with the Apple Pencil; a feature called Math Notes can write out expressions like you would on a piece of paper, and the app will solve the expressions live as you scribble them—plus various other cool live-updating math features. (These new Math Notes features work in the Notes app, too.)
