This study will evaluate the feasibility and acceptability of DockTales, a mobile health tool designed for adults with chronic pain. DockTales supports pain and sleep tracking through brief diaries, body-map pain reporting, reflective journaling, visual summaries, and optional AI-supported interaction. The study will be conducted completely remotely. Participants will complete 2 weeks of DockTales use and 2 weeks of REDCap-based daily monitoring, with the order randomized. The main goal is to determine whether DockTales is usable, acceptable, engaging, and practical for adults with chronic pain compared with standard REDCap monitoring.
