The Cargolink-app is designed as simple as possible to make it easily understandable. Around 15 people tested our app with the mvp prototype and most of them stated, that they immediately understood what they needed to do without explanation. As Fabio and I both are not professional programmers, the app does not work fast und stable enough. Because of this, it will be further developed. We also designed an Icon for the app to be viewed on the homescreen of the users smartphone. Below you can see all the screens we created for the app.
