Why ranking is the more useful direction
If you already know you are short of something, a lookup app is no help at all. It can tell you what is in a banana; it cannot tell you what to eat instead. Ranking answers the question you actually have: where do I get this?
That question comes up constantly in clinic. A patient on a blood-pressure plan needs potassium. A vegan needs B12 and iron. Someone recovering from surgery needs protein and zinc. In every case the useful answer is a short list of foods, ordered, with realistic portions attached — which is exactly what a ranking is.
It is also the natural companion to tracking. VitalFill tells you which nutrients you fell short on; NutriRank tells you what to do about it. I built them as two halves of the same idea, and I wrote about that reasoning in why I built a nutrient tracker instead of another calorie counter.
Common questions
Is it really free?
Free to download and free to use, with a core set of nutrients. Pro unlocks the complete set — $2.99 a month, $19.99 a year, or $39.99 once. Try the free version first; I would rather you decide you need Pro than be nudged into it.
Can I try before installing?
Yes. The ranking tool on this site runs the same query against the same database for six nutrients, with no account and nothing stored. It is the honest way to see whether this is useful to you.
Where does the data come from?
The USDA National Nutrient Database for Standard Reference — laboratory-analysed values, and the dataset behind most nutrition labelling and nutrition software in the United States. Nutrient targets come from the NIH Dietary Reference Intakes.
Who made it?
I did — Gily Ionescu, MS MD, an internal medicine physician with a master's degree in human nutrition. The reference values are the ones I would defend in a clinical discussion, which is a higher bar than most nutrition apps set.
