A more useful Siri
It takes a bit of work to make Siri better in iOS 12. The voice assistant has a few new tricks, like the ability to turn the flashlight on, get information about celebrities, or ask for the calorie count of an avocado. But the real improvement is the Shortcuts feature in Settings.
You can record your own Siri commands, based on common tasks and recommendations from recent app usage. For example, you can add one that starts a voice memo recording when you trigger Siri and say “Captain’s Log,” or one that Googles your name when you say, “Google me.”
The built-in options in Settings are limited, but Apple is going to release a standalone Shortcuts app that will let you build more complex custom commands.
