Scan, Import or PDF

Document scanner with auto-crop, gallery import, or PDF. CestApp reads the receipt on the spot and opens it in review

100% On-Device

ML Kit OCR runs locally. No image or receipt is ever uploaded, and there is no account to create

Smart Categorization

Auto-sorts items into 11 categories and learns from your corrections per store

Spending Analytics

Monthly trends, category breakdowns, store comparisons, and top items

See How It Was Read

Every receipt shows the zones CestApp found over the image. If the reading is off, redraw them or crop to the receipt and it reads again

Your Data, Your Backup

Export every receipt, item and category to a JSON file. Phone and tablet layouts, dark mode, English and Spanish

Your data never leaves your phone

CestApp uses Google ML Kit for on-device text recognition. On iPhones with Apple Intelligence, an on-device model repairs the receipts the OCR read badly. No images or receipt data are ever uploaded. Everything is stored locally on your device.
