With the release of iOS 12 last week came a new automation app, Shortcuts. In it, users can map everything from simple workflows like sending an email, to complex actions surrounding home automation, navigation, and communication on your return home from work each evening. Each is done with a trigger, a sort of if-this-then-that workflow that starts with one thing, and then completes a list of tasks in a defined order.
You can grab the shortcut here.
