Works great for my needs!
I use the free version. You can use “aisles” if you want to see the total cost of all “dairy” items, etc., or you can shop without the aisles. If you want to remove something from your cart, just swipe left on the item. The tax part didn’t seem to work for me but that isn’t crucial to me. All I wanted was something to calculate the costs that was a bit more convenient to use than a traditional calculator. For me, this app works great!
