## Description

What2Know reads the label so you don't have to. Scan any product and get a clear, plain-English read on what's inside, for everyone in your home.

NO BARCODE? NO PROBLEM.
Scan a barcode for an instant, unlimited, always-free lookup. No barcode, like wine, local, specialty or cosmetics? Tap "Scan the label" and What2Know reads the packaging straight from a photo.

SCAN ANYTHING
Food, supplements, cosmetics, pet products, and wine. One app for the whole shelf.

BUILT FOR YOUR HOUSEHOLD
Set up a profile for each person and pet with their allergies, diet, and ingredients to avoid. Every scan tells you who it suits, and who should skip it. Save products to your Family Shelf.

INGREDIENT & HAZARD SCREENING
We check the ingredient list against published watch lists from public health authorities and flag additives and ingredients of concern.

BETTER CHOICES
When something doesn't fit, see cleaner alternatives in the same category, right in the app.

What2Know is an informational tool, not a medical device. It does not diagnose, treat, or prevent any condition. Allergen and hazard results reflect detection in the text we were able to read, not a guarantee of safety. Always read the physical product label and consult a qualified professional for medical or dietary decisions.

FREE VS. PREMIUM
Barcode scanning is free. What2Know Premium is an auto-renewing subscription ($4.99/month or $19.99/year) that unlocks unlimited AI "Scan the label" photo reads, unlimited household profiles, and product alerts. Payment is charged to your Apple ID at purchase. Your subscription renews automatically unless cancelled at least 24 hours before the end of the period, and you can manage or cancel anytime in your App Store account settings.
