Why Nutrio

An honest app for knowing what you eat

There are many ways to score a food. Nutrio picks transparency: an open formula, official sources and zero commercial interests. Here is why it is worth using.

100% independent

No ads, no sponsored brands and no selling your data. No manufacturer can pay to look better. The score answers to the data and nothing else.

Open formula

No secret algorithms. The score comes from a public formula you can read in full under "How it works", weightings and thresholds included.

Grounded in science

Every additive warning links to its real source: EFSA re-evaluations, IARC monographs, European regulation and peer-reviewed studies.

Millions of products

We use Open Food Facts, the largest open food database in the world. Scan practically any barcode in the supermarket.

No accounts, no tracking

No sign-up, no email address. Your settings stay on your phone; we never see them.

Free

Nutrio is free. A project built to help you understand what you eat, not to sell you anything.

Additives explained

More than 475 additives with their risk level, what they are, what they may cause and why — in measured language, never presenting suspicions as certainties.

Alerts that are yours

Tick what matters to you — palm oil, gluten, lactose, vegan, nut-free… — and Nutrio flags it on every product you scan.
