Diese App ist der Vorgänger von BundesMessengerX, sie bleibt nutzbar und erhält wichtige Sicherheitsupdates, jedoch keine neuen Funktionen mehr. Für eine aktuelle, stetig weiterentwickelte App mit moderner Oberfläche und zusätzlichen Funktionen für den Behördenalltag, empfehlen wir ausdrücklich die Nutzung des BundesMessengerX. --- Der BundesMessenger generell ist eine sichere Messaging-Lösung für die Öffentliche Verwaltung. Von der BWI für die Behörden in Deutschland. Ziel ist es, eine moderne & sichere Zusammenarbeitsplattform auf Basis von Open Source für Deutschland zu schaffen, die sich den Bedürfnissen und Vorgaben der Deutschen Verwaltung anpassen kann. Mit dem BundesMessenger kannst du auch beruflich so kommunizieren, so wie du es privat von anderen Messengern gewohnt bist. Der Messenger nutzt das Open-Source-Protokoll Matrix und wurde für maximale Sicherheit konzipiert. Tausch dich in 1:1-Chats oder in Gruppen aus und versende Textnachrichten, Dokumente oder Mediendateien – auch Sprachnachrichten und Umfragen sind natürlich möglich. Jede Kommunikation wird automatisch und durchgängig VERSCHLÜSSELT.

Stackfield's advantage is iOS requirement (13.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
