We employ data from the Adolescent Health and Development in Context Study—a representative sample of urban youth ages 11–17 in and around the Columbus, OH area—to investigate the feasibility and validity of smartphone‐based geographically explicit ecological momentary assessment (GEMA). Age, race, household income, familiarity with smartphones, and self‐control were associated with missing global positioning systems (GPS) coverage, whereas school day was associated with discordance between percent of time at home based on GPS‐only versus recall‐aided space‐time budget data. Fatigue from protocol compliance increases missing GPS across the week, which results in more discordance. Although some systematic differences were observed, these findings offer evidence that smartphone‐based GEMA is a viable method for the collection of activity space data on urban youth.
