Shareable Grocery List Phone App

My husband and I have been using "AnyList" for the past year or two. It's a free iPhone app where you can make a grocery list and share it and whoever you share with can update the list immediately. So I can text my husband that I'm going to the store, and he can check the list and add anything I've forgotten. 

There are several nice programs that do this; we like some of the features in AnyList. I like that I can make shortcut lists of frequently-bought items, so I can go through that list and tap on the ones I need and they get added to the shared grocery list. I only rarely use the recipe features, but they are very helpful for shopping for a recipe you make regularly.
