Design Principles
Keep the interface simple
The MANGER interface is really simple, and we do not expect many user input, in general just navigation.
To reach this goal, we decides to outsource the configuration of MAGER to a call line.
Configuration like this on a mobile phone is just confusing.
Design for error
As the configuration is outsourced, people cannot destroy their MANGER application.
With the setting area you can jsut determine the layout, that means which information you want to see, but nothing else.
Experience
Everybody who can use a mobile phone, can use MANGER.
Immediate Feedback
MANGER reacts to input immediately. If no information is available, it tells this to the user.
