Shopping for someone with food allergies? Scan any barcode and know in 3 seconds if it's safe — for you or every family member. Peace of mind in the palm of your hand.
AllergenScan tells you in seconds whether a food is safe for you or your family — before it ends up in the cart.
Scan a barcode or photograph an ingredient label. AllergenScan checks against your personalized allergy profile and delivers a clear Safe, Caution, or Danger verdict with color-coded results you can read at a glance.
