A native iOS health-monitoring app that uses your phone's front-facing camera to measure vital signs in real time, then leverages AI to deliver personalized health insights — all without wearables.

Built at DeltaHacks.

• Camera-Based Vital Scanning — Uses the SmartSpectra rPPG SDK to capture heart rate and breathing rate from a 20-second face scan via the front camera. No wearable hardware required.
• AI Health Insights — Sends today's vitals plus historical baselines to Google Gemini (gemini-2.5-flash), which returns a structured, personalized insight report covering heart rate trends, breathing patterns, and actionable suggestions.
• Risk Score — Computes a 1–100 risk score by measuring how far today's readings deviate from the user's personal normal band (15th–85th percentile over the last 30–60 days).
• 7-Day Trends — Interactive Swift Charts showing heart rate, breathing rate, and stress over the past week, with tap-to-expand detail views and trend summaries.
• Healthcare Map — MapKit-powered search for nearby hospitals, clinics, urgent care, and pharmacies with distance display, one-tap directions, calling, saving, and sharing.
• Family Sharing — Share health updates with family contacts and view their heart rate trends and mood indicators.
