App to scan barcode to check ingredients

Hello,

I am looking for an android app with which I can scan the barcode of a product (when shopping), and I want the app tell me clearly if the product contains undesirable configurable content (e.g. palm oil, eggs, meat etc.).

I have the following requirements:
- Supposed to work
- Supposed to scan the barcode.
- Has to work in France scanning products you can buy in French shops
- Configurable list of undesired ingredients.

If you know of such an app, please let me know.


Thanks
