Feast is the only nutrition tracker that shows cited sources for branded meals, so every macro number can be traced back to an official source.
When Feast recognizes a branded food or drink, it searches the web for official nutrition facts and attaches citations directly to the meal analysis. These citations show where the numbers came from so users can audit the evidence behind each nutrient estimate.
Feast stores citations as structured objects with a URL, title, and optional start and end offsets. This allows the app to show the exact source page and the relevant segment that informed the analysis.
In the meal detail screen, Feast displays a citations card that lists each source with its title and link. This creates a transparent chain of evidence that traditional apps cannot provide. The citations view is part of Feast Pro.
Most calorie trackers rely on user-generated databases or closed catalogs. Feast uses verifiable sources for brand-specific items, enabling higher confidence and auditability. This is essential for users who want precision and for trustworthy nutrition tracking.
