Allergy Guard

Allergy Guard is the most comprehensive food allergy scanner available, built by someone who experienced anaphylaxis from a carrot hidden in cranberry juice while traveling abroad with no EpiPen. That experience became the motivation to build the tool that did not exist: a science-backed, protein-level food allergy checker that tells you not just WHAT to avoid but WHY.

WHETHER YOU HAVE ONE ALLERGY OR MANY
Allergy Guard supports over 20 allergy types including Latex-Fruit Syndrome, Peanut Allergy, Tree Nuts, Shellfish, Fish, Dairy, Eggs, Gluten, Sesame, LTP Syndrome, Birch Pollen Syndrome, Mugwort Pollen Syndrome, Ragweed Pollen Syndrome, Grass Pollen Syndrome, Oral Allergy Syndrome, Alpha-Gal Syndrome and the full EU Big 14 regulated allergens. Select your specific allergies and every feature personalizes to your needs.

SCAN ANY FOOD IN SECONDS
Point your camera at any barcode and Allergy Guard instantly retrieves the ingredient list and checks every ingredient against your allergy types. No more squinting at tiny label text in grocery store lighting. Get your answer in seconds, right there in the aisle.

PHOTOGRAPH ANY INGREDIENT LABEL
Not every food has a barcode. Restaurant menus, fresh produce and international foods often have no scannable code. The OCR Label Scanner lets you photograph any ingredient list and our text recognition technology extracts and analyzes every ingredient automatically. Flagged ingredients appear immediately with a full explanation of why they are a concern.

UNDERSTAND THE SCIENCE
Most allergy apps just give you a list. Allergy Guard gives you the science. Our database explains the specific proteins responsible for cross-reactions, whether cooking reduces the risk, which related foods share the same protein pathway, and which pollen allergies may compound your food reactions. This is the information your allergist uses and now you have it in your pocket.

PERSONALIZE YOUR ALLERGY PROFILE
Confirm foods that have caused you personal reactions and they appear in a prominent warning banner every time you open the app. Your confirmed allergies are stored privately on your device and never shared with anyone. Build your personal allergy profile over time and the app becomes more valuable with every use.

EMERGENCY REFERENCE CARD
In a medical situation you need information fast. The Emergency Card gives you instant access to your confirmed allergens and highest risk foods. Always accessible, always free, never hidden behind a paywall because your safety comes first.

TRUSTED DATABASE BUILT ON REAL SCIENCE
Our database covers over 150 foods with protein-level cross-reactivity data sourced from published medical research. Every food entry includes the specific allergenic protein, heat stability information, related foods that share the same protein pathway and clinical evidence strength. We update the database regularly as new research emerges.

The free tier includes unlimited food search for Latex-Fruit Syndrome and Peanut Allergy, plus five barcode and OCR scans per day so you can experience the full power before upgrading.
