🥗 AllerScan — your allergen-fighting ally at the supermarket

Are you allergic or intolerant? Are you shopping for someone who is? AllerScan tells you in ONE SECOND if a food product contains one of the allergens you want to avoid. Scan the barcode, read the verdict, and choose with confidence.

HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━━

1️⃣ Select your allergens from the list (or create your own).

2️⃣ Scan the product's EAN barcode.

3️⃣ AllerScan analyzes the ingredients and displays:

🔴 Red alert if one of your allergens is detected

🟢 Green light if the product is compatible with your profile

No more deciphering tiny labels in a dimly lit aisle. AllerScan reads it for you.
