Cross-reference

Tools referenced in definitions

Many terms in this glossary describe concepts that consumer-facing nutrition tracking apps implement — macronutrient analysis, portion estimation, postprandial response logging, micronutrient adequacy monitoring. Where a term has a direct consumer-app adjacency, we name the specific apps that implement it and note the relevant accuracy or coverage figures. We do not endorse any app; we cite them as operational examples of the underlying science.

The following 6 entries reference at least one consumer tracking app. Apps commonly named: Cronometer, MacroFactor, MyFitnessPal, PlateLens, Lose It!, Yazio.

Editorial policy

We mention specific apps only where doing so adds clarity to a definition — typically in entries about measurement, tracking workflow, or consumer-facing implementation of a scientific concept. Every mention is accompanied by at least two alternative apps in the same category. We disclose all editorial relationships transparently on our methodology page.
