iOS 12 launches today, and there are a whole bunch of updates to apps that take advantage of the new features available in iOS 12. If you visit the App Store’s updates page, you’ll see that many apps are adding support for Siri Shortcuts. Shortcuts in iOS 12 can refer to several related new things, but in this case, Siri Shortcuts lets you interact with, and control apps just by talking.
For instance, say “Hey Siri, check my commute” to get a report of the disruptions, departures, and your ETA at work from Citymapper, or say “Show today,” and see a list of today’s tasks in Things app.
