Apple Reminders has a feature to remind you when you are leaving or arriving at a location. It's super useful! But it's not super low friction to add to a Reminder via UI (it's buried at the bottom of the edit screen), so it's a feature ideally suited for a voice-based reminder. Nevertheless, nobody implemented it.

Hey, I made that!

It's a great feature! I was demoing it to my parents over Thanksgiving and forgot about the lack of Siri support, and of course it failed. Parents were excited when I mentioned it but now won't be using it. Ah well.

Super useful feature; thanks. I used it to help me remember the names of people I saw often at places I ate at or worked out of.

I can set location-based alerts manually. For me, or for those who voluntarily already share their location with me. No reason Siri can’t drive those same notifications.

Edit: to be clear, Siri doesn’t. Still no reason it shouldn’t be able to.
