This app works by creating a category then making a list within that category. You tap the plus button at the top right to create the category for the shopping list. Once the category has been created, you tap on it to go to the list. Tapping on each list item will put a checkmark next to it to signify that the item is done.
The delete button on the top right will clear the whole list. You can also swipe left to delete individual items.
