In the end, matt was fully designed in Figma, and the app was fully implemented. However, the widget was not implemented due to lack of time. The app is customizable and shows appropriate recommendations depending on the time of the day. If a recommendation is pressed, matt redirects you to the appropriate app.
A user test was made to figure out how matt was perceived. We asked four people what words they would use to describe our designs. We got the following collections of words:
As we were designing the app to be friendly, we found these results to be good. Even though the word friendly wasn't mentioned itself, many other positive words were and show that our design is perceived in a positive way.
Another important question is how effective matt is in keeping you from scrolling on your phone. To really find out if matt is effective, a more long-time evaluation would have to be conducted and the widget would have to be implemented. Since the widget is such an integral part of the concept, it was hard for us to try the app and get a feel for if it works or not. The concept itself seems promising since matt could act as a trigger for new habits in the way Stawarz et al. (2015) describes. It's easy to imagine that this effect could be lost over time though, and therefore the efficacy of the app would have to be evaluated longer term.
