Scan
First
A short, plain guide to what a two-second scan tells you about your food — and the handful of things it can't.
- Why the same food carries two different carb numbers depending on which country labelled it
- The one figure that silently changes every other number on the panel
- Why “0 g” is a legal threshold, not a promise
- Which sugar alcohols behave nothing like each other
- A sixty-second check you'll still be using next year
The app that does the arithmetic
The guide is about reading food accurately. Ketolock is about not having to do the maths every time — photograph a plate or scan a barcode and it gives you an editable net-carb estimate.
It's an estimate and a starting point. It doesn't diagnose anything, measure anything in your blood, or detect gluten or allergens — it can't tell you a food is safe.
