Apple Reminders has native grocery lists now. The collaboration feature (a household can keep just one shared grocery list) and auto-categorizing by store section are serious time and frustration savers. No "oh shit, I left the list at home", no "I could go to the grocery store while I'm out, if we need anything... but the list's at home...", no manually organizing the list, no grocery-list-by-text. It's so nice, saves far more time than any faff it introduces (I'd agree that without the collaboration and auto-categorizing, grocery lists on phones would be more trouble than they're worth)

(I know other apps have also done it, but having it on a built-in is really handy and it works well)
