Die Quadriga‐Mobile‐App ist ein Hilfsmittel zur Inventarisierung Ihrer Inventargegenstände, den so genannten 'Komponenten'. Sie können sehen, in welchen Räumen sich welche Komponenten Ihres Inventars befinden, und im Rahmen von Bestandskontrollen feststellen, welche Komponenten fehlen oder in andere Räume umgestellt wurden. Die App arbeitet zusammen mit der PC‐Anwendung Quadriga‐IT. In dieser Anwendung werden die Daten zu den Komponenten bereitgestellt und per E‐Mail versandt. In der App können Sie die per E‐Mail erhaltenen Daten dann importieren und mit der Inventarisierung beginnen. Nach Ihrer Bestandskontrolle schicken Sie die Ergebnisse Ihrer Arbeit per E‐Mail zurück und werten Sie mit Quadriga‐IT aus.

Thanks to EBF Contacts, your team can access professional contacts easily, securely, and even offline while on the go—on iOS and iPadOS. Automatically synchronized from sources such as Exchange O365/On-Premise or your CRM system. The Global Address List (GAL) or other address books can be easily connected, giving you real-time access to all your contacts. EBF Contacts can even be accessed with Siri and CarPlay. EBF Contacts uses the SMS Fraud Extension, if the user activates it. This makes the company contacts information available in the iOS phone app to display the name and other information about a caller. EBF Contacts does not block phone numbers or messages. CallKit must not be enabled to use the app. The user can skip this step on initial use.

Verdict
The clearest difference is update cadence: EBF Contacts at every 6 weeks against Quadriga's every 17 months. Quadriga's advantage is iOS requirement (8.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
