Overview

Description

GroceryList is the new, ideal app for keeping track of your stock of groceries at home, as well as keeping track of groceries when supplies run low. Our app allows you to scan the barcode on any grocery item you buy, and keeps an inventory of it in a database. With this database, users can keep track of their stock, as well as form a grocery list of items to buy next time you go shopping.
