This is pretty rad: With Siri Shortcuts and Face ID, I can say “Hey Siri, record this,” and then look at my iPhone, and it’ll record a voice memo. Great for when I come up with an awesome guitar riff.
You can do this without Face ID, but you need to unlock the iPhone to do the actual recording. With Face ID I can look at the phone and it starts. You just have to make sure it’s propped up where it can see you.
