Apple has made widgets for most of its own apps, and it has even redesigned quite a few of them for this release. (Note that you could previously have widgets on a weird Today View shelf to the left of your home screen, accessible by swiping over to it.) As on Android, widgets come in different sizes (just three for iOS: small, medium, and large), and you can stack them together to swipe between them. There's also a "Smart Stack" widget that claims to automatically offer the widgets you need at the right times and locations that you'd need them.
