A couple of weeks ago I discovered, installed, paid for Grocery App:
A smart shopping list, recipe manager, meal planner and inventory tracker for iPhone, iPad, and Apple Watch.
It’s brilliant! I share recipes and shopping list with Deb now, and it is smart. Thanks @manton


Widget support lets you make a list or few available on lock screen swipe-right so you do not have to unlock your phone at store. You can't mark off items without unlock but, great for those essential items. Probably get even better in iOS 16 (beta).
