FAQ

Frequently asked questions

What does GlutenScanner cost?

The Android app is free to download and use. The iPhone version is a small one-time purchase. There is no subscription, no ads and no in-app purchases - on either platform.

Can I trust the answer?

GlutenScanner is a helper tool, not a guarantee. The verdict is based on ingredient lists from open databases and manufacturers, which can be incomplete or outdated. With coeliac disease or severe intolerance, always read the packaging yourself as well.

What if a product isn't found?

Then you can take a photo of the ingredient list - the app reads the text and assesses it. You can also submit the product so we add it to the database for everyone else.

Does it work without internet?

Your previous scans and favourites are stored on the phone and can be viewed offline. New lookups need internet, since the product is looked up in the database.

Which allergens does it check besides gluten?

The app also flags the other EU allergens it finds in the ingredient list - among them milk, egg, nuts, peanut, soy, fish, crustaceans, celery, mustard, sesame, sulphites, lupin and molluscs. Gluten remains the app's main assessment, though.

Important: GlutenScanner is a helper tool, not medical advice. Databases and automated lookups may be incomplete or outdated. If in doubt - especially with coeliac disease or severe gluten intolerance - always read the ingredient list on the packaging yourself.
