Scan the barcode
Looks the product up and tells you whether it contains gluten, may contain traces, or carries a regulated gluten-free claim.
Know what's really in it
Scan a barcode or the ingredients list itself, and get a straight answer about gluten - including the "may contain traces" warnings that other apps bury or skip.

What it does
Or scan the ingredients list
Photograph the label and your phone reads it on the device. Works on any product, even one no database has heard of. Nothing leaves your phone to do it.
See which ingredient
The gluten source is marked in the list, so you can see why - in ten languages, including the German and Italian labels that turn up in European shops.
Why we built it
We are a family with celiac disease close to us. The apps we tried told us a product was "safe" without telling us how they knew - and treated a voluntary "may contain traces" warning as if it meant something precise. It does not. So we built the app we wanted: one that shows its work, and says plainly when it does not know.
(Celiac disease is spelled "coeliac" outside the US - same condition.)

Where the data comes from
Product data comes from Open Food Facts, an open, community-maintained database, used under the Open Database License. Product photos are used under CC BY-SA. Ingredient lists change and databases lag behind - so the app tells you how old its information is, and says when it does not know instead of guessing.
