I'd also like to be able to ask "How many steps have I taken today?" Siri responds with "I can't answer that on your iPhone but you can find it in the Health app: Open the Health app"
This may feel like a big ask considering the majority of the basics aren't covered on the platform I'm using, but compound questions would be wonderful – "show me the thirty largest US cities" "remove any that do not have a moderate climate" "which one has the lowest cost of living?"
If platforms already provide these services and I'm simply using the wrong one – oops.
