The app does the scanning.
The web is the library. The app is where the database grows: on-device barcode reading, on-device OCR of the ingredient list, and a one-minute flow to add a product everyone can look up afterwards.
Scan
ML Kit barcode reading, instant cache hits, and a tradition toggle on every result.
Add
Three photos. OCR runs on your phone; only the cropped kosher symbol is sent for reading.
Share
Every result links to its web page, so “here’s why it’s okay” is one tap away.
Until the stores list the app, the web scanner looks products up in your mobile browser.
