GlutenTrace: Gluten Scanner

GlutenTrace reads the ingredient list and tells you what is actually there — including what it cannot be sure about.

Scan a barcode, or photograph the ingredient list itself. Your phone reads the label using Apple's built-in text recognition, so you get an answer even for products no database has yet.


WHAT MAKES THIS DIFFERENT

Most gluten apps give you a green tick or a red cross. Real labels are rarely that simple.

"May contain traces" is a voluntary warning. There is no legal threshold behind it, and manufacturers choose whether to print it at all. Researchers have measured gluten above 20 ppm in roughly the same share of products carrying the warning as those without it.

So we never show it as a flat red. We tell you what that line can and cannot tell you — and we word it differently depending on whether you have celiac disease, a wheat allergy, or gluten sensitivity, because the advice genuinely differs.

We also tell you when we are not sure. Unqualified "starch", "flavoring", "caramel color" and yeast extract can all carry gluten without the label resolving it. We name them.

In the U.S., only wheat has to be declared as an allergen. Barley and rye can hide in "natural flavors" and spices. When your phone is set to the U.S., GlutenTrace treats those words as unresolved instead of giving a green answer, unless the product is labelled gluten-free.


HOW IT WORKS

• Scan a barcode to look the product up
• Or photograph the ingredient list — read on your phone, not on a server
• Gluten sources are marked in the ingredient text, so you can see them yourself
• Set your condition once: celiac, wheat allergy, or sensitivity


ALWAYS FREE

• Unlimited scanning, barcodes and ingredient lists
• The safety verdict, and the reasoning behind it
• Which ingredient is the gluten source
• Your own list of products, shareable with whoever does the shopping
• No account, no ads, no data selling

GlutenTrace Pro adds the full ingredient list with gluten marked in red, a product photo whenever the database has one, how old the data is, unlimited history, every article, and restaurant cards in six languages for travelling. It supports a family-run project instead of advertising.


WHO IS BEHIND IT

GlutenTrace is built by the family behind Renmel (renmel.dk), a Danish site about celiac disease. The articles in the app are ours, built on published research, with the disagreements left in rather than smoothed over.


IMPORTANT

GlutenTrace is an informational tool, not medical advice. Ingredient data can be incomplete or out of date, and manufacturers change recipes. Always check the packaging yourself — especially if your reaction is severe.
