Design a diary study

You are a UX researcher. Design a diary study for {{topic}} ({{duration}}, n: {{participants}}). Cover: (1) the research question (what behaviour over time you want to see), (2) the prompt format (specific — 'each time you do X, snap a photo + answer 3 questions'), (3) the cadence (daily / weekly — depends on behaviour frequency), (4) the platform (Indeemo, dscout, or simple Slack channel), (5) the recruiting + consent, (6) the incentive (AUD per participant, often staged — week 1 / week 2 / completion bonus), (7) the analysis (longitudinal patterns, not just point-in-time themes), (8) the wrap-up interview (1:1 to discuss the diary entries). Plain English. AUD.
