About What2Know
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 and unlimited, with no account needed. Premium unlocks unlimited AI "Scan the label" photo reads, meal scans, unlimited household profiles, and product alerts.
What2Know Premium is an auto-renewing subscription at $4.99/month or $19.99/year. Payment is charged to your Google Play account at purchase, and your subscription renews automatically unless you cancel at least 24 hours before the end of the period. You can manage or cancel anytime in your Google Play subscriptions.

What’s new
Version 2.3.1 · Updated September 21, 2026
A cleaner, calmer look: white screens, and colour only where it means something, like a warning for someone in your home. Drinks are now judged as drinks, with figures per 100 mL. Your Family Shelf, Home and History now apply the same checks as the full report. A first look at Instacart on your Family Shelf, coming soon. Plus clearer wording and smaller fixes throughout.
User reviews
Absolutely fantastic! The new upgrade made it much clearer. I don't go to the grocery store without! Dining in restaurants with the scanner makes it able to read the nutritional value on my meals! AMAZING!!!!
