Question 1

Is there a free version?

Accepted Answer

Yes — everything you touch daily is free. The diary, the AI input, products and recipes work without paying anything.

A subscription opens micronutrients: vitamins, minerals, fibre and your own targets for them. That is the single part of the app the money pays for.

We don't run ads and we don't sell data, so there is no other way for this to pay for itself.

Question 2

Where do the calorie and macro numbers come from?

Accepted Answer

From USDA FoodData Central — the food composition database published by the US Department of Agriculture. Our catalog is built on top of it: every entry points at a reference row, and calories, protein, fat and carbs are read off that row. The AI never invents a number. It decides which food you meant and how much of it there was; the composition comes from the reference.

Question 3

What is USDA FoodData Central?

Accepted Answer

A public database in which foods are broken down into nutrients. Most nutrition apps and a good deal of research lean on it, because the numbers there come from laboratory analysis rather than from packaging. We use three of its datasets. Foundation is current lab analysis. SR Legacy is the standard reference frozen in 2018. FNDDS holds survey foods composed from recipes — that one is why plain “milk” or “fried potatoes” resolves at all, without you picking a cut and a doneness level. When two datasets describe the same food, the lab analysis wins over the modelled composite.

Question 4

How accurate is the AI at counting a meal?

Accepted Answer

It does two things: works out which food you named, and how much of it there was. Both come back editable — you see the matched product and the grams before anything is saved. So the error lives in the quantity, not in the composition. “A bowl of rice” is a guess; “180 g of rice” is not. The composition behind it is as accurate as its USDA row. When a food was matched to something close rather than exact, the card says so instead of quietly pretending.

Question 5

How much can I trust the micronutrients?

Accepted Answer

They come off the same USDA rows as the calories — twelve vitamins, ten minerals, fibre and saturated fat, by day and by period, against your own targets. Two honest limits. A reference row describes a typical food, not the exact one in your fridge, and soil, feed and processing move micronutrients around far more than they move protein. And USDA measures foods on the American market — for staples that changes nothing, for local products it can. Read them as a trend and as a way to spot holes, not as a lab report on your day.

Question 6

What if a food isn't in the catalog?

Accepted Answer

Create it once: name, composition per 100 g, the portions you actually use. After that it searches and repeats like any other entry. For packaged goods there is a second source, Open Food Facts, where the numbers come off the label. We deliberately keep it below USDA: a label is what one manufacturer declares about one package, usually six nutrients out of thirty, and nobody measured them.

Question 7

Can I use it on my phone?

Accepted Answer

Yes. FoodIQ is a web app: it opens in the browser and installs to the home screen, where it runs full-screen without any browser chrome around it. There are no separate App Store or Google Play apps yet. The same interface works on a phone, a tablet and a desktop.

Question 8

How does payment work?

Accepted Answer

In crypto, for a month or for a year. There is no auto-renewal: nothing is ever charged on its own, you extend when you decide to. When a subscription runs out, the diary and everything in it stay where they are — micronutrients simply stop being shown. Nothing is deleted.

Question 9

What happens to my data?

Accepted Answer

We don't sell it and we don't show ads — the subscription pays for the app, so there is no second business model that would need your diary. The diary is yours and is published nowhere. A recipe becomes public only at the moment you publish it yourself.
