I made my own Android app to help me track spending. Doesn't let you scan receipts but it has very robust categorization ability. You can export and import files and also has foreign currency.
$493.71 over the last 7 years. At an average (just a guess) meal cost of 5, that's 98.7 visits overall. 1.18 visits a month, which is lower than I expected. Also turns out I love their breakfast a lot.

Tool: Driller - Expense Manager Didn't like anything on the market. They weren't detailed enough, so I made my own app.
