Open Food Facts is an open, collaborative effort to try to make more sense of food and food packagings. A bit like Wikipedia, but for food. Using smartphones, you can scan any food item and get detailed and structured data about what you're about to buy/eat.
If the item is not yet in the database, you can help by taking a picture, so that next time there will be detailed facts.
You can peruse it at http://world.openfoodfacts.org
We have Apps for Android (http://android.openfoodfacts.org) iPhone (http://ios.openfoodfacts.org) Windows Phone (https://www.microsoft.com/en-us/store/apps/openfoodfacts/9nb...)
It's Open Data, so feel free to use the API in your apps and let your users contribute to end this (OdBL licence)
Also, we're looking for volunteer contributors and developers from all over the world to: - translate it to more languages - add food from your fridge - enhance the apps and web version
