The Challenge
Patients with conditions like diabetes and hypertension had no easy way to correlate lifestyle factors (sleep, diet, stress) with symptom spikes — leading to reactive rather than proactive care.
The Solution
We built a cross-platform React Native + Expo app integrating Apple Health and Google Fit. An on-device LLM (via Core ML) analyses multi-week trends and surfaces actionable insights without sending raw health data to the cloud.
