Veggie Check is an app that allows users to scan USA food products to help determine if they are vegan or not. Currently the back end is not ready to be open source, but it will be soon. Also note that there is no API key, yea I know it will be hard to test without haha I'll make one soon.
This was made using React Native + Expo
It'll be made public. There is some stuff I want to fix, but I promise the data and api will be open source and free to use!
