A preparation app could let users collect their own questions, priorities and practical reminders before an appointment. It could organise those notes into a simple list that the user controls.
The app should not diagnose a problem or decide which concerns deserve medical attention. If prompts are provided, they need appropriate review and clear wording. Private notes require understandable storage choices and an easy way to delete or selectively share them.
Start with a plain checklist and test whether users can find their most important questions during a conversation. Include large text, offline access and a printable option where useful. The aim is to support communication with a clinician, without presenting generated suggestions as personalised medical advice or a substitute for contacting a healthcare service.
