Photograph an ingredient list and dtect shows which of your allergens it contains. Direct matches, such as milk, appear in red. Trace warnings such as "may contain hazelnuts" appear in amber. dtect reads the printed label itself, so it requires no barcode and no product database. This helps with imported goods, small brands and labels in English, German, French, Italian, Dutch or Spanish. Text recognition can misread words. dtect supports you in reading a label but does not determine whether a product is safe, so always check the packaging. - 14 EU allergens built in, each of which can be switched off - Your own allergens, rated High or Warning - Direct match in red, "may contain" trace in amber - Nutrition table per 100 g, 100 ml or serving, with your thresholds for fat, saturates, sugar and salt - Gluten, lactose and fructose check - Country of origin with flag - History of your last 100 scans, with optional product name - Report an incorrect result directly from the result screen All processing takes place on your phone. dtect needs no account, collects no analytics and makes no network connections. The only permission it requires is camera access. Requires iOS 16 or later on iPhone.
