Diary studies are often applied in HCI research to collect qualitative user impressions. Unfortunately, the period between creation of an diary entry and the later reflection is way too long, which leads to a limited currentness and contextually. This eventually results in incomplete or misinterpreted data. In this paper we present Storyteller, a mobile application which allows a quick creation of diary entries and encourages users to reflect on these in-situ through a storytelling approach. We argue that this can lead to more accurate and substantial qualitative insights.
