List - Ordered Shopping List!

With this app we want to solve the problem of wasting time inside the supermarket!
- When you add a Supermarket to the app, enter the items you buy / want to buy, indicate the sector to which they belong and their category.
- Select the items you want to add to the shopping list and automatically I would have a progressive order inside the supermarket, avoiding wasting time going back and forth looking for the various products you want!
