Dalil
Dalil looks up ingredients and E numbers, reads an ingredient list from a photo or pasted text, and shows what named public rulings say about what it finds, with a link to each source. It works with no network connection and collects nothing.

What it is not
Dalil is not a fatwa and not a certification. It is a reference that shows its sources so you can check them, and it is not a substitute for your scholar or for a certifier.
