Nextcloud Deck (F-Droid Store) allows viewing and editing team tasks in ViOffice Deck and informs you immediately about changes in the task stack.
Passwordmanager
Passman is the perfect complement if you want to make use of the ViOffice password manager integrated in ViOffice. The app constantly synchronizes passwords with your device and allows password-secured access to your information stored there.
Calendar und Contacts
DavX5 (F-Droid Store) or also OpenSync synchronize your calendars and contacts from ViOffice Calendar and ViOffice Contacts directly with the smartphone, so that you always and everywhere keep the overview.
However, if you have activated two-factor authentication in your account, you must first create an "app password". To do this, open the VO Cloud in your web browser and select the "Security" menu item under Settings (top right). Scroll all the way down here and create a new "App Password". Use this to log in to Calendar Sync App. Alternatively, you can also initiate the process via the Nextcloud Sync app, which supports two-factor authentication. In this case, no app password is required, but your usual login.
