“30 Days:” An EMA Diary Mobile App & Web Tool

Abstract

As HCI researchers, we are constantly searching for ways to improve the approaches in which we engage with our participants, especially when engaging with vulnerable populations about sensitive topics like online risk experiences. For this reason, we developed “30 Days,” a cross-platform EMA diary mobile app and web tool that collects contextualized data by engaging and motivating teens to report on their daily online experiences. We developed 30 Days to be tailored to the needs of researchers using experience sampling with teens. This interactivity demonstration provides an overview of the “30 Days” system.
