CleanScan: PDF Scanner OCR

CleanScan turns your phone camera into a high-quality document scanner. It automatically detects edges, removes shadows, and produces clean, sharp PDFs — the kind that look like they came from a flatbed scanner, even when you photographed the page under uneven light.

FIND ANY OLD RECEIPT IN SECONDS
Every scan is searchable. Need to find what you spent on a specific day — six months ago, a year ago? Search by date, amount, or the shop's name, and the matching invoice comes straight back. No more digging through a shoebox of receipts.
