The ‘PRO TRACE' App allows you to trace a number of our products along the supply chain. By scanning the code you can retrieve information about where the product comes from, how it was processed, quality and sustainability information, and even recipe ideas. Currently we have various fish and meat products in our traceability solution for you to explore; many more will follow. PRO stands for 'Product'. Get more information about a product and its way from the source up to you in the market. PRO stands for 'professional' and applies to our professional customers as well as to the professional quality of our service. PRO means 'for': METRO is actively engaged in Traceability and thereby in Transparency, which are both demanded nowadays. TRACE is the actual performance we offer: PRO TRACE makes Traceability feasible for every customer. Just scan the code on the product with your smartphone and learn more about the origin, processing and METRO sustainability aspects. Track the journey of a number of our products. You can find the code on the packaging of pre-packed products. For fresh products, the code will be printed on the label after the weighing process. Alternatively, you can retrieve information by entering the GTIN and LOT number from your invoice under ‘Numeric Input’ or on the website www.metro.de/protrace.

Die BackApp ist eine einfache und moderne iOS App, die Dir beim Verwalten deiner Rezepte und beim Planen deiner Backtage hilft. Die BackApp verwaltet Deine Rezepte und ermöglicht es Zeitpläne mit den richtigen Zutatenmengen und Temperaturen für den Backtag zu erstellen, außerdem kannst Du Rezepte exportieren und importieren um sie an Freunde oder Bekannte weiterzugeben. Rezepte werden mit ihren Schritten und Zutaten erfasst. Zusätzlich können Schritte andere Schritte als Zutat haben. Dies ist zum Beispiel für Vorteige nützlich. Die BackApp berechnet dir die notwendige Temperatur von Schüttflüssigkeiten, meist Wasser, unter Berücksichtigung der Raumtemperatur. Zusätlich gibt es auch automatische Zutatenartenerkennung bei häufigen Zutatennamen Mit der Planungsfunktion kann man entweder vom gewünschten Fertigstellungszeitpunkt aus oder auch von einer Startzeit die Zeit- und Mengenplanung eines Rezepts erstellen und dann exportieren. Die BackApp erstellt dir dafür einen Zeitplan mit Schritten, Daten und Zutaten basierend auf deinen Eingaben. Hierbei werden auch die Zutatenmengen für die gewünschte Anzahl an Broten, Brötchen, etc. … errechnet. (z.B gibt es ein Rezept mit Mengen für 10 Baguettes, man möchte aber lediglich 2 Baguettes machen)
