This contribution sheds light on how people experiencing homelessness in Germany make sense of an app designed with them in mind and whether using it would be of benefit to them. However, it must be acknowledged that the app has yet to be developed. “Urban figurations of social control,” a term we use to refer to the social conditions of homelessness in Germany, give rise to a significant loss of trust as well as a state of vulnerability, feelings of loneliness, and limited agency for people experiencing homelessness. Drawing on a group discussion with 12 people experiencing homelessness that took place in Germany in 2019, our findings demonstrate that the respondents project particular fears and desires onto the use of the potential app. Whenever they fear surveillance and institutional control, they wish to be invisible to the app. On the other hand, their desire to access resources and information (food, places to sleep, housing) and to meet with peers in order to create meaningful social relationships requires their visibility. Thus, navigating between visibility and invisibility by way of a smartphone involves situationally and strategically constructing a safe environment for their digital participation, helping them to reduce their vulnerability and loneliness and restore their agency. Moreover, in that the app is used as a means of rendering assistance to homeless people (and highlighting the grievances associated with this) that is visible to others, the respondents challenge the current framing of homelessness. The supposed system of help is revealed to be the social problem itself.
