my favorite shopping app

This is very useful in the store since it correctly finds the product location by aisle.
The free in store wireless means I am not using cellular data.
It also has my Shoppers Club Card.
I see other reviews where they have to log in regularly. I used to have this problem, but I have not had it for the last year (iPhone 5C & iPhone6S+).
