Build a focused health journal that starts with a personalized tracking protocol for the patient's condition and asks only a few adaptive questions each day. It should import available measurements from Apple Health and common wearable sources, record medications and injection sites, and generate a concise appointment packet showing symptom changes, possible associations, adherence, and an editable timeline. The product should describe associations without presenting them as diagnoses or treatment recommendations.

Patients increasingly have useful measurements scattered across wearables, health platforms, medication logs, and clinical portals, but still need to assemble their own story for appointments. The signals show sustained use when tracking produces credible evidence for clinicians and abandonment when manual entry outweighs the value of the resulting analysis.
