What we get asked most often.

Yes for the core of the app: the food diary, barcode scanning, the Nutri-Score, macros, micronutrients and recipes, with no cap on meals, no advertising, no account and no card details to enter.

Two paid options exist: a Premium subscription, which adds AI included, long-term trends and CSV export of the diary; and a one-off Lifetime purchase, where the AI runs on your own API key (BYOK) rather than being included. Without a key, Lifetime works without AI. The full JSON backup of your data, re-importable into the app, stays free: only the convenience of a spreadsheet is paid for, never the way out.

No. There is no sign-up, no email to hand over, no password. You open the app and log your first meal.

On Android through Google Play and on iPhone through the App Store. The nutri-track.fr website does not run the app: it presents it and points to the stores.

Your food diary stays on the phone. There is no account, so no server holding your diary, and no sync between devices.

One consequence worth knowing: if you uninstall the app without exporting, your history goes with it.

No: no resale, no advertising, no ad trackers, no profiling. The detail, provider by provider, is in the privacy policy.

Counting, recipes and the Nutri-Score work without a connection. Two features need the network, and only when you trigger them: scanning a product absent from the bundled database, which sends nothing but the barcode to Open Food Facts, and the optional AI assistant, which sends the meal you choose to have read to a third-party provider.

We do not write that the app is “100 % offline”: that would be false.

From public databases, never from in-house estimates: the ANSES Ciqual table as the primary source, USDA FoodData Central as a top-up when a food is not in the French table, and Open Food Facts for scanned branded products.

Where a value does not exist, the app writes “not reported” rather than showing a zero. Full detail on the sources page.

Every generic food carries its Ciqual record number. Type the food name into our public lookup tool, note its 5-digit code, then search for that code on ciqual.anses.fr and compare the values per 100 g.

653 Ciqual records can be browsed this way.

It is calculated with the public Santé publique France algorithm, from the composition of the food.

On a branded product, the score depends on the values declared in Open Food Facts: if the product entry is incomplete, the score can differ from the one printed on the packaging. That is a limitation of the data, not an editorial choice.

Yes, and it helps. Write to us with the food name as it appears in the app and, if you have it, its record number. A confirmed error is fixed at the source and ships in an app update.

The target the app suggests is a reference point calculated from the information you give it, for a general adult population. You can change it by hand, but not below a safety floor: 1,200 kcal a day for a woman, 1,500 for a man, 1,400 if sex is not given. Every route to changing it goes through that floor, manual entry included.

For a profile under 18, an unconfirmed age, or a declared pregnancy or period of breastfeeding, the app shows no numeric target at all: it offers to log meals and points to a healthcare professional.

This reference point is not a prescription and does not replace the advice of a healthcare professional. Radish provides neither diagnosis nor medical advice.

Eleven vitamins and minerals. When the food comes from our public databases, the value comes from them and the source is shown.

When you add a food our databases do not know (photo, scan), micronutrients may be estimated — they then carry an “estimated” label on screen.

When the table gives no content for a nutrient, the app shows “not reported”: never a zero. That missing value does not go into the daily total, so your actual intake may have been higher than what is shown.

This is why a daily total is a minimum, not a measurement — a low figure does not mean a deficiency. Only a healthcare professional can establish a deficiency, through a blood test.
