ShieldGuard · Ancaster, Ontario

Your clinic gave you a list of chemicals. The supermarket did not.

Point the camera at a label. Check it against your Patch, Prick, or Intradermal results. Green or red. In the aisle.

Toggle Fragrance Mix I (eight chemicals, many names) versus a clean label. Result is against your sample list — not a generic “top 8 allergens” guess.

Your sample avoid-list includes Fragrance Mix I positives. Watch the hits light up.

Built after a real patch test

Fragrance Mix I is not one ingredient — it is eight chemicals, each with other names. The clinic paper is useless in aisle 7. So the app puts that list on the phone.

Clinic paper

A long avoid-list after Patch / Prick / Intradermal testing — dense, medical, easy to leave at home.

Eight names expand

One “mix” becomes a web of synonyms on the label.

Supermarket aisle

Shampoo, cleanser, food — tiny print. Ask: is this safe for me?

How it works

Three steps. Your list.

Tap a card. Also supports Halal, Kosher, and common free-from checks.

Who it’s for

Not a feature dump — a pocket use-case

Just left the allergy clinic

You walked out with a chemical avoid-list. AllergyGuard turns that paper into something you can use while shopping — Patch, Prick, or Intradermal positives, on your iPhone.

Shopping for a parent or child

Keep their triggers on the phone when they are not with you in the aisle.

Halal · Kosher · free-from

Common diet and free-from checks sit beside your personal chemical list.

Honest limits

Helper, not a doctor

AllergyGuard is not a lab and not a guarantee. Formulas change. Always read the physical label and follow your clinician.

Personal helper against the list you entered — not a medical device.
OCR can miss tiny or curved print — you can edit recognized text before checking.
When in doubt, leave it on the shelf and ask your allergist.

FAQ

Plain answers

Patch vs Prick vs Intradermal?

Patch tests often find contact allergens (skin). Prick and Intradermal are typically used for immediate-type allergies. AllergyGuard lets you save positives from the test type you actually had — in plain language, on your phone.

Halal / Kosher / free-from?

Besides your chemical avoid-list, you can use common Halal, Kosher, and free-from checks when shopping. They do not replace certified packaging or religious authority guidance.

Does it replace my doctor?

No. It is a helper for the aisle. Diagnosis, treatment, and medical advice stay with your clinician.
