INGREDIENT & HAZARD SCREENING We check the ingredient list against published watch lists from public health authorities and flag additives and ingredients of concern. BETTER CHOICES When something doesn't fit, see cleaner alternatives in the same category, right in the app. What2Know is an informational tool, not a medical device. It does not diagnose, treat, or prevent any condition. Allergen and hazard results reflect detection in the text we were able to read, not a guarantee of safety. Always read the physical product label and consult a qualified professional for medical or dietary decisions. FREE VS. PREMIUM Barcode scanning is free and unlimited, with no account needed.
