Does this food contain gluten? Check the barcode or ingredient label with Celiscan and see what the result is based on. Built for people with celiac disease and anyone shopping for a gluten-free diet. From a familiar snack to a product you have never tried, Celiscan helps you review the available information before you decide. CHECK THE BARCODE. READ THE LABEL. Scan a packaged food barcode to look up its product information. No match or missing ingredients? Photograph the ingredient label for another way to check. SEE WHY A PRODUCT GETS ITS RESULT Review the ingredient flags, gluten-free label information, and warnings available for the product. Results distinguish Gluten-Free, May Contain, Contains Gluten, and Not Sure Yet. MAKE ROOM FOR UNCERTAINTY An ingredient list without an obvious gluten source is not the same as a gluten-free claim. Celiscan checks for gluten sources and caution signals, including oats and “may contain” warnings. When evidence is missing, a result can say Not Sure Yet. BUILD YOUR PANTRY Save products, keep favorites, and revisit previous scans. Keep the information you have already checked close at hand for your next grocery shop. HOW TO START 1. Open the scanner and choose barcode or label. 2. Scan the package and review the result and its reason. 3. Save the product to your Pantry for later.

Celiscan's advantage is update cadence (every 6 days vs every 6 weeks) and iOS requirement (17.0 vs 26.0). On price, rating, ads and device support there is nothing between them.
