Scan it, see the carbs
One barcode — net carbs done for you

No more flipping packages over and doing the math on your phone's calculator. One scan gives you the net carbs and a clear keto rating, and what you ate is logged to your diary for the day.

Before you install — where the product data comes from

The app's interface is fully in English, but the product database is built from items sold in South Korea and Japan. Barcodes from other markets will usually not be found yet, and product names and ingredient lists are stored in their original language. If you scan something we don't have, you can add it yourself from a photo of the nutrition label — that works anywhere.

🍽️

Just photograph the nutrition label and the AI reads the values for you.

⚠️

Sugar alcohol warnings

Detects sugar alcohols that can affect blood sugar (maltitol and others), flags them up front, and counts them conservatively in the net carb math.
