Scan barcodes. See what's really inside.

Klenz scans packaged foods and highlights additive markers in the ingredients — so you can make more informed choices at the store.

How barcode scanning works

Point your camera at any barcode on a packaged food. Klenz looks up the product and shows you ingredient insights — a breakdown of the additives in the product.

Additive markers highlighted

Klenz checks the ingredient list against a database of food additive markers. Each additive also lists available research studies on the additive if available.

Scan while you shop

Generate a grocery list from your meal plan in Klenz, then scan items at the store before you buy them. Check for additives right in the aisle — so you can pick the cleanest option on the shelf before it goes in your cart.

Part of the Klenz nutrition tracker

Barcode scanning is one of the tools inside Klenz alongside photo, voice, and search meal logging, restaurant menu scanning, AI meal plans, and the Klenz Score. Together they give you a full picture of your food — 31 nutrients tracked across 7 health areas: Brain, Heart, Bones, Immunity, Skin, Energy & Focus, and Eyes.
