I built a receipt organizer and tracker app on iOS in May this year and now it has just past $200 in monthly recurring revenue and >$500 in December. Before this I have been collecting my own receipts and scanning them into a private website I built for myself, then one day I was like, why don't I make it into an app so it is easier to use and I can share it with others?

What do you use for OCR, I wonder

if it's LLM isn't that too expensive (or flaky if cheap) to be scalable?
