The everyday intimacies of friendship and flirting are not typically explored in hook-up app research, nor is there much reflection on the intimacies of researching these media. This paper considers flirting and friendship as practices and methods that broaden the scope of current hook-up app research. We ask what these intimacies can produce to expand research approaches (and thus knowledge) of hook-up apps. As users and researchers of these apps, we consider negotiations of flirting and friendship between researchers and research participants by exploring what it means to research with intimacy. Attention is given to the connections, conversations, and intimate encounters within hook-up research that are mostly absent from existing presentations of research findings. We suggest that greater attention to peripheral and intimate communication between researchers and participants can offer valuable methods for queering otherwise stabilised ways of knowing, using, and researching these platforms. Adding to the queer ethnographic tradition, we demonstrate how a processual and affective approach to hook-up app use encourages researchers to make visible our connections to the media we research, and how these relate to the intimacies they foster.
