This app is intentionally simple to use and designed to be like the shopping list you write on a piece of paper and stick on the fridge. The bonus is that the fridge is always in your pocket when you go out so you won't leave home without it (unless you leave your phone at home of course).
Everyone's device in your family can view and update the list. Just sign in using the same username and password on each device. And multiple username accounts can be used on the same device if you wish. Just logout from one and login with another.
It starts with a default "Groceries" list but adding more lists and removing unwanted lists is a breeze.
Simple to add items, just type it in and hit the "Add Item" button. Mark off the items as you shop by pressing on the item and remove them by hitting the trash can. Can also remove all marked items when you are finished shopping.
Username can be anything you like (unless it is already in use), does not need to be an email address or anything else personal. The app does not need to store any personal details.
