Food Scanner Mobile App

This app allows a user to scan UPC barcodes for food/grocery items, and then report any ingredients which have been flagged as sensitive.

This allows users with food allergies or sensitivies to more easily identify foods they can and can't eat.

In this repo

This repo contains:

• Android native mobile app code (Kotlin)
• iOS/Android React Native mobile app code (Javascript)
• Firebase backend function (Typescript)

User scans are stored in Firebase backend. Only the UPC code and product title are stored in the database, as per TOS of Edamam API.

Users must authenticate with Firebase authenticatin (currently only Google Sign-In supported) to use the service.
