MedAlert

🌟 Inspiration

India faces a healthcare crisis where millions struggle with medication adherence, lack of access to emergency support, and fragmented caregiver coordination. We wanted to build a platform that ensures health support is always just a tap away—especially for the elderly, chronically ill, and rural populations.

💡 What it does

MedAlert is a cross-platform healthcare companion that helps users:

• Track medications and get smart refill reminders
• Monitor and analyze vital health metrics
• Share medical profiles and updates with caregivers
• Respond to emergencies with one-touch SOS and live location
• Securely store health data using Supabase with Row-Level Security

🛠️ How we built it

• Frontend: React Native with Expo, using Expo Router and TypeScript for structure and type safety
• Backend: Supabase for database, authentication, and real-time updates
• Database: PostgreSQL with user-specific RLS for each table
• Storage: AsyncStorage for local caching and Supabase Client for sync
• Authentication: Supabase Auth with token-based session management

🚧 Challenges we ran into

• Implementing Row Level Security correctly across tables
• Designing a mobile-first UI that also scales to web
• Syncing offline and online states without data loss
• Handling real-time updates across medication and health stats

🏆 Accomplishments that we're proud of

• Built a HIPAA-aligned data flow using Supabase
• Enabled seamless emergency support with live location and health info
• Created a role-based caregiver management system
• Achieved cross-platform support with a unified codebase

📚 What we learned

• Best practices of real-time data sync using Supabase subscriptions
• Secure authentication and database isolation with RLS
• Designing for accessibility in healthcare UX
• Managing state effectively with React Context and hooks

🔮 What's next for MedAlert

• Integrate pharmacy APIs for automatic refills
• Add multilingual support for wider accessibility in India
• Include health record scanning and OCR
• Implement AI-driven health alerts and anomaly detection
