Abstract
The usability and acceptability of patient-centered mobile health tracking apps among most clinical populations are unknown. This mixed-methods feasibility study evaluated the usability and acceptability of the Health Storylines app among 32 adult radiation oncology patients in a 2-week trial. Data were collected via pre- and post-app use surveys and digital analytics. Participants accessed the app platform a total of 711 times. The overall usability of the Heath Storylines app was rated favorably, and 81% of participants reported the app easy to use. This study provides beginning evidence of the usability and acceptability of this type of mobile health tracking app in adult oncology patients.
