A pantry or repurchase estimate is off — can I correct it?

Yes. Open the pantry (in an open list at the top via the title bar, or via „⋯“ → „Pantry“) and tap the fill ring on the product — choose „empty“, „¼“, „½“, „¾“ or „Full“. „Full“ resets freshness and shelf life; „Used up“ takes the product out of the pantry.

After just a few such corrections, the estimate becomes noticeably more accurate. And if the item is already on a list, the hint disappears on its own.
