- The app describes barcode lookup for known products, plus use-first lists, expiry reminders, and a 12-month timeline.
Field notes
The calculators are presented as standalone browser tools, while the iPhone app is positioned for keeping supply counts current over time. Its listed features include barcode lookup that works only where a product is known, a use-first list, expiry reminders, and a 12-month timeline. The page also links to sources and method information and explicitly says its guidance is independent rather than official.
