Point the camera at a label. Check it against YOUR Patch, Prick, or Intradermal results. Green or red. In the aisle. Works offline. I built it after a patch test. Fragrance Mix I is eight chemicals, each with other synonyms names. Save your positives, photograph the ingredients, see Safe or Risky for you, not a generic list. Also Halal, Kosher, and common free-from checks. A helper, not a doctor. Formulas change. Always read the bottle. By ShieldGuard, Ancaster, Ontario.
