I keep two receipt piles on the phone so the scan never leaves it

I had two piles. LLC in one, side hustle in the other. The receipts sat on the table. The spreadsheet was whatever I typed at 11pm.

I built XPENZNET on Expo / React Native so the scan stays on the phone. On-device OCR: Apple Foundation Models + Vision first, llama as the fallback when Vision lies about the total. Android ML Kit is in the code but not in a store yet.

The hard part was not the camera. It was trusting folio fields and keeping a separate ledger per pile.

PDF export is free. CSV is a one-time IAP. No account. Nothing leaves the phone until you share the file.

App Store: https://apps.apple.com/app/id6744484775
If you want the receipt → CSV writeup: https://www.xpenz.net/receipt-scanner-csv-for-accountant/

If you have shipped on-device OCR: what did you use when Vision invented a total?

Not legal advice.
