PRODX

Nutrition scanner

Nutrition facts, readable in one scan

Sugars, saturates, salt, protein, fibre: the numbers are on the back of the pack, in small type, with nothing to compare them to. PRODX lays them out, adds the official Nutri-Score where one exists, then calculates a score that accounts for your profile — and shows you its working.

From the nutrition table to a score you can question

  1. 01

    The per-100 g values are pulled

    Energy, carbohydrates and sugars, fat and saturates, salt, protein and fibre, as recorded for that product.

  2. 02

    Each value gets a reference point

    A number on its own says nothing. PRODX marks whether a value is high or low for this kind of product.

  3. 03

    The official Nutri-Score appears where it exists

    That is the public 2023 algorithm, computed from the product alone. It does not depend on you, and PRODX does not alter it.

  4. 04

    Your score is calculated and itemised

    The PRODX score, 0 to 100, accounts for your profile. “Why not 100%?” lists what took points off, one item at a time.

What a nutrition scan gives you

  • Two readings, kept distinct

    Nutri-Score describes the product. The PRODX score describes the product for you. Both are shown, and never conflated.

  • A deterministic calculation

    Fixed rules, published in the app's methodology. The same inputs always give the same result — no AI is involved.

  • The score, itemised

    Every point taken off is attached to a readable reason, not to an opaque number.

  • Comparison and alternatives

    Compare two products side by side, or browse products from the same category ranked by nutritional quality.

Why two people do not get the same score

The nutrition table is identical for everyone; what it means is not. A given salt content does not read the same way whether or not you are managing your blood pressure; a protein content does not weigh the same against different goals. PRODX never edits a product's values — it weights them against what you have declared, then shows the reasoning so you can argue with it.

A concrete example

Two breakfast cereals carry the same Nutri-Score. You compare them in PRODX: one has markedly more sugars per 100 g, the other more fibre. Depending on your profile the scores separate, and the breakdown names exactly which line of the table made the difference.

What the numbers say, and what they do not

Values come from Open Food Facts and can be incomplete or reflect an older formulation. Where a value is missing, PRODX shows the gap and does not penalise the product for it. Values are given per 100 g or 100 ml, which makes products comparable but does not correspond to a real serving. And a score is a summary: it says nothing about your diet as a whole, and PRODX provides neither medical nor dietetic advice.

Common questions

What is the difference between Nutri-Score and the PRODX score?
Nutri-Score is the official 2023 algorithm, computed from the product alone and the same for everyone. The PRODX score, 0 to 100, accounts for your profile. Both are shown separately.
Is the score calculated by artificial intelligence?
No. The calculation is deterministic and follows fixed rules documented in the app's methodology.
Does every product have a Nutri-Score?
No. Where one is not available, PRODX says so rather than estimating one.
Do the values correspond to a serving?
They are given per 100 g or 100 ml, the standard basis that makes two products comparable. A real serving may be larger or smaller.
