Install the app

The app runs on iOS and Android. Install it from the respective store or the build provided by your operator.

In preparation

Screenshots and store links will follow once the app is published.

On the login screen tap Server: <host> to expand the server picker. The default is demo.nuclos.de.

Known servers appear as chips – tap to select.
Use Add server to enter a new host (e.g. demo.nuclos.de) and confirm with „+“.
Servers you no longer need can be removed via their chip.

Multiple instances

You can store several servers and enable biometric login per server independently.

Then sign in.
