There are apps for what you want. There are lots, but you can start by checking out Expensify. They have a free plan that lets you scan up to 10 receipts per month. I'm sure there are totally free options, I just know this one is proven. This should help you search for alternatives. Try a google of "free Expensify alternative". I just don't have one to recommend as I only ever used Expensify for a time (for work).
