Our method, in full transparency
How Volumeal estimates your calories, where the values come from, the limits we own up to — and who is behind the app.

How we estimate your calories
You photograph your plate (or scan a barcode, or dictate your meal). An analysis service identifies the foods and their amounts, then Volumeal derives the calories and macros. Because any estimate from an image carries a real margin — portion, density, hidden fats — we show the result as a confidence range (e.g. 420–560 kcal) rather than a fake exact number.
To track your weight, that range and the trend over time are enough: it is more honest, and it avoids fixating on a decimal that means nothing.
Where the values come from
The values do not come from nowhere: they rely on public reference databases and established scientific formulas, cited below and directly in the app.
What Volumeal is not
Who is behind Volumeal
Volumeal is built by a small independent team, in France, founded by Can Ozmen. We created Volumeal after seeing that calorie counters show a single, precise, reassuring number… that is often wrong. Our stance: measure honestly, owning the uncertainty rather than hiding it.
Our editorial policy
Our content and calculators rely on verifiable official sources (cited and linked). We do not publish invented statistics or studies, we show a range when the measurement is uncertain, and we update pages as guidance evolves. Spotted an error? Email us at [email protected].
