Stamp Identifier for iOS

AI-assisted philatelic identification powered by a Cloudflare Worker and Google Gemini.

Stamp Identifier stores your scan history locally and sends selected stamp photos to its backend only when you start an identification. The backend forwards the images and prompt to Google Gemini, then returns structured fields the app saves with your scan.
