Simple Chronic Condition Day-Tracker Without Symptom Logging Fatigue
People with migraines, IBS, chronic pain, and autoimmune conditions want to track daily patterns over time. Existing apps like Migraine Buddy demand 15+ fields per entry. Users abandon them within weeks because the logging burden exceeds the benefit. A builder on HN shipped dotsjournal: just tap a dot for your day and see patterns emerge. The demand is for pattern recognition with minimal input.
The core insight is that adherence beats precision. A 1-5 severity dot tracked daily for 6 months is more clinically useful than a detailed 15-field log tracked for 2 weeks then abandoned. Ship with ONE condition (migraines), ONE input (severity tap), and ONE output (calendar heatmap). Add conditions and optional fields later. Medical PDF export for doctor visits is the feature that drives word-of-mouth.

Health tracking apps optimize for data richness at the cost of adherence. Detailed logging yields better insights but users quit within weeks. The gap is a 5-second daily check-in (severity dot + optional tags) that accumulates into useful pattern visualizations over months. dotsjournal proved the concept on iOS. Android and multi-condition support are wide open.
