I use the List Ease app to help keep me organized in a simple to use format. Once you scan or manually add an item, you can send it to your grocery list or back to your pantry list with just one click. No need to re-enter items as they go back and forth between the two lists.
You can also create your own lists, categories and so forth so it’s not just for groceries.
I have included the link below. Check it out!
