Healthica
Smart-band health monitor with on-device glucose prediction
A Flutter app that streams vitals from an ESP32 smart band over Bluetooth Low Energy and predicts blood glucose on the phone with TensorFlow Lite. No server sits in the real-time path.
- ESP32 firmware sends vitals plus 27 derived features as JSON over BLE GATT at 1 Hz
- Glucose regression (HR, SpO2, temperature, GSR) runs on-device; linear and neural models compared, then quantised
- Tiered health alerts, a supervisor view, GSR-guided breathing mode, Supabase auth and history
