I learned recently you can do this with screen time on iOS.

So for us, we very clearly distinguish "a user labelled this item" vs "we guessed it was this label".
I'll keep you posted!
On top of that we try to get further accuracy by using user information to help us find the context. We call it a Personal System, a repo of knowledge and learned preferences heavily tailored around each individual user. We're just in beta now but definitely put your email down if you want to try it out eventually!
