Step 2 Demand for early symptom self-monitoring

Problem

Parkinson's disease takes an average of 1-3 years to diagnose, and most patients fail to recognize early symptoms (micro-tremors, motor slowness, handwriting changes) or dismiss them as normal aging. Among adults over 50 who experience hand tremors, it takes an average of 8-14 months before visiting a neurologist, during which no symptom data is recorded, leaving doctors with no meaningful information at the first consultation.

Solution

Uses smartphone accelerometer sensors to measure hand tremor frequency (4-6Hz is the suspected Parkinson's range), tracks handwriting changes (touchscreen writing analysis), and records gait patterns through a daily 30-second test. Visualizes weekly/monthly trend reports and sends 'neurology visit recommended' alerts when suspicious patterns are detected. Data can be exported as PDF for submission to doctors at the first visit.

Target: Adults over 50 experiencing hand tremors or motor slowness, or adults in their 40s-50s with parents over 60
Revenue Model: Premium Subscription: basic tremor measurement Free, trend analysis, Report, and alerts ~$3/month. Family sharing (parent data linked to child's dashboard) ~$4.50/month.
