Receipts pile up because nobody wants to retype the amounts. OCR removes that barrier: scan the receipt, extract the text, and name the file with what you will search for later.
The receipt workflow
- Photograph the receipt flat with even lighting; thermal paper fades, so capture it early.
- Run OCR to extract the text — vendor, date and amount.
- Name the file: "2026-08-16 - office supplies - 42.50".
- File it under the project or expense category it belongs to.
On-device vs cloud OCR
Cloud OCR sends each receipt photo to a server. On-device OCR keeps the image and the text on your phone, which is the simpler privacy default for expenses and reimbursements. Either way, verify amounts — OCR reads characters, it does not understand receipts.
An app I built for this
Private Text Scanner is an offline OCR app for Android: free daily allowance, rewarded ads for extra scans, and a one-time purchase for unlimited scanning (no subscription). No account required; recognition runs on the device. I am the developer of Private Text Scanner.
