THIS IS THE ONE. By far the best shopping-list app with TRUE MULTI-STORE FUNCTIONALITY: 1) Add an item to the master list, 2) choose the stores it appears in, 3) when checking off that item in one store, it’s checked off in all of them. Simple, intuitive UI; fully customizable (create & rearrange aisles by store; add notes to items), and no clutter or feature-creep (no recipes, etc.). SO happy with this app. Just wish the search & add-item features worked in tandem.
