Simplest thing in the world, and practical. Add an Alexa Show in the kitchen, connected to AnyList. She can say “Alexa, add Flour to my shopping list”, then we can use AnyList on all of our iPhones to check things off in the grocery store. AnyList even organizes the shopping list by Aisle (after you set it up). My wife uses it every day. Once in a while, I will be in the grocery store shopping, and I will find something pretty funny on the shopping list like XXL condoms. She has fun with it.
