Über die Onlineverwaltung gibt es sehr viele Möglichkeiten, den Messenger an den eigenen Bedarf anzupassen. Bei Personalwechsel erhält ein neuer Mitarbeiter kurzerhand einen Zugang und kann bei allen Mitarbeitern automatisch in die Kontakte eingefügt werden, auch wenn er das für seine persönlichen Kontakte (keine Telefon-oder Maildaten angegeben) deaktiviert hat. Vorherige Mitarbeiter werden entfernt. Toll auch das Verwenden des Firmelogos. Da kann sich selbst ein kleines Unternehmen chic präsentieren. ### 5/5 — Simple, secure *2025-01-23* Does what it says on the box with understated Swiss efficiency. **Developer response:** Thank you for your review! ### 3/5 — Handhabung bei Smartphonewechsel und Desktopversionsnutzung ziemlich unhandlich *2025-01-16* Der Wechsel von Smartphone zu neuem Smartphone ist nicht einfach. Sicherheit geht vor, ist aber manchmal auch nicht wirklich kundenfreundlich. Die Desktopversion auf Mac- Desktop ist derzeit scheinbar nicht zuverlässig instalierbar. Hat irgendwann einmal gut funktioniert. Derzeit gar nicht auf Mac hinzubekommen. **Developer response:** Vielen Dank für Ihr Feedback. Gerne helfen wir Ihnen, diese Probleme zu beheben. Bitte kontaktieren Sie unser Support-Team: help@threema.ch ### 5/5 — Great but emojis would be beneficial *2025-01-11* I wish I was able to 🩷😂👌🏻👍🏻🥲😮 messages. There is already the green thumb, red thumb and star but would love to have more options! **Developer response:** Thank you for your review! We will be happy to discuss your feature request. However, we cannot tell you if or when it will be implemented. ### 3/5 — Anmelden unmöglich *2024-12-03* Passwort und Benutzerbame waren richtig aber es hat trozdem nicht angenommen! Die Schule hat auch versucht zu helfen,leider nix gebracht. Ich muss jetzt warten bis ich neue abneldedqten bekomme,aber sonst war alles sicher und ich konnte problemlos chatten **Developer response:** Gerne helfen wir Ihnen, dieses Problem zu beheben. Bitte kontaktieren Sie unser Support-Team: help@threema.ch ### 2/5 — immer wieder Fehler. *2024-11-12* Immer wieder bei einigen Geräte plötzlich Probleme mit Push-Meldungen. Somit bleiben Nachrichten unentdeckt. Aktuell können von vielen Geräten keine Videos mehr versendet werden. Sehr ärgerlich, zumal Threema Wochen braucht, um Bugs zu fixen. **Developer response:** Gerne helfen wir Ihnen, dieses Problem zu beheben. Bitte kontaktieren Sie unser Support-Team: help@threema.ch ### 5/5 — Saubere Sache *2024-10-26* Ich habe in den letzten Jahren diesen Messenger als sehr vorteilhaft kennen gelernt. Unkompliziert und meine Handynummer ist einfach nicht sichtbar. Das ist mir total wichtig. **Developer response:** Herzlichen Dank für Ihr positives Feedback! ### 5/5 — Einfache Administration und sehr guter Support *2024-08-08* Gutes Feedback unserer Kolleginnen und Kollegen in der Verwendung von Threema Work und Threema Web möchte ich gar nicht thematisieren. Ich möchte einmal die wirklich intuitive Administrations-Webpage loben! Die stetige Weiterentwicklung im Sinne von uns Kunden schätze ich außerordentlich! Und der Supportkontakt (den ich wenige Male nutzen musste) ist einfach zu erreichen, reaktionsschnell, zielstrebig und dazu noch äußerst freundlich! **Developer response:** Herzlichen Dank für Ihr positives Feedback. ### 4/5 — Ganz ok *2024-05-27* Es fehlt nur noch die Funktion einer Abwesenheit ! Das wäre extrem wichtig und hilfreich **Developer response:** Herzlichen Dank für Ihr Feedback! Wir arbeiten kontinuierlich an neuen Funktionen. Um keine Erwartungen zu schüren, die ggf. enttäuscht werden müssen, machen wir aber bewusst keine verfrühten Angaben. ### 5/5 — Funktioniert sehr gut *2024-03-05* Die App wird als stark gesichertes berufliches Kommunikationsmittel genutzt und funktioniert reibungslos. Man muss beim Einrichten einmalig die ID exportieren sowie ein Passwort vergeben, den Threema Safe brauch es dafür nicht zwingend. Der speichert die Nachrichten nur in der Cloud. Ein Smartphone Backup erfüllt den gleichen Zweck. Genauso ein Smartphonewechsel, bei dem alle Daten mitgenommen werden. Die können nur erst wieder genutzt werden, wenn die exportierte ID inkl. Passwort wieder eingegeben wurde, sonst kann jeder auf die Threma Daten zugreifen. Bei mir funktionieren die Benachrichrigungen. Die hängen ohnehin am iOS Benachrichtigungssystem, welches als unzuverlässig und unsicher eingestuft wird. Muss also nicht an der Threema App liegen. **Developer response:** Herzlichen Dank für Ihre Rezension! ## Frequently asked questions about Threema Work. For Companies ### What is Threema Work?
