• Scanned ingredients match by what they are: "sugar" is sugar, "oats" are oats; anything uncertain is left for you to confirm, never guessed. • Online lookups show every reading with its source sentence and only accept figures about the food you asked for. • "Look up all missing" proposes values beside the closest foods already in your list — nothing is applied until you choose. • Substitutes list related foods first. Saved recipes ask for servings.
