Keto Barcode Scanner & Carb Checker

How it works

Keto Peek is a fast, free keto barcode scanner and carb checker designed for the grocery store. You don't need an account to get started. Just choose how you want to look up a food:

  • Scan a barcode: Use your phone's camera to scan the UPC or EAN code on the package.
  • Upload a photo: Snap a quick picture of the nutrition label. Our system will read the macros and ingredients.
  • Type a name: Search for a brand or generic food to estimate its keto compatibility.

What you get

Within seconds, you'll receive a clear verdict: Great, Good, Caution, Avoid, or Unknown. We calculate the net carbs, check for added sugar, and flag ingredients that might pause ketosis.
