MediTrack - Personal Health and Medication Management App

MediTrack — Personal Health and Medication Management App

A comprehensive health companion that helps users track medications, appointments, symptoms, and vitals. Targeted at chronic illness patients, elderly users, and caregivers managing multiple patients. Think of it as a smart personal health assistant that keeps everything organized in one place.

The Problem It Solves

• People with chronic illnesses manage 5+ medications daily and frequently miss doses
• Health records are scattered across multiple hospitals, apps, and paper files
• Caregivers managing elderly parents have no centralized tool to track multiple patients
• Patients forget to log symptoms between doctor visits, leading to poor diagnosis
• No single app combines medication tracking, vitals, appointments, and document storage

Tech Stack

• Frontend: React Native (cross-platform iOS and Android), Expo
• Backend: Node.js, Express.js
• Database: MongoDB (health records, medications, appointments, vitals history)
• Auth: JWT with biometric authentication (Face ID, Fingerprint via Expo LocalAuthentication)
• Notifications: Firebase Cloud Messaging for medication reminders and appointment alerts
• AI: OpenAI API for symptom analysis and drug interaction warnings
• Storage: AWS S3 with AES-256 encryption for health documents and lab reports
• OCR: Tesseract.js or Google Vision API for lab report scanning
• Wearables: Apple HealthKit and Google Fit SDK integration
• Deployment: AWS (backend), Expo EAS (mobile builds), MongoDB Atlas (DB)

   • Suggested alternatives pulled from drug database
   • Links to medical references for each interaction

2. Lab Report Scanner

   • Upload a photo or PDF of a lab report
   • OCR extracts key values (HbA1c, creatinine, CBC, lipid panel, etc.)
   • Values stored and plotted on trend charts automatically
   • Highlight values outside reference range

3. Doctor Sharing

   • Generate a shareable health summary for an appointment
   • Includes recent vitals, medications, symptoms, and lab values
   • One-time link with expiry for privacy
   • Printable PDF format

4. Emergency Health Card

   • Accessible without unlocking the app (like iOS Medical ID)
   • Shows blood group, allergies, critical medications, emergency contacts
   • QR code that first responders can scan

Monetization Strategy

• Freemium model — free for single user with basic tracking
• MediTrack Pro — caregiver mode, unlimited profiles, AI insights, document storage
• Family Plan — manage up to 5 family members under one subscription
• Hospital and Clinic B2B — white-label version for patient management
• Pharmacy Partnerships — refill reminders deep-link to pharmacy ordering apps

Why This Project Stands Out

• Solves a deeply personal and high-stakes problem with real-world impact
• React Native, biometrics, wearable SDKs, OCR, and AI together cover a wide range of advanced mobile concepts
• HIPAA-relevant architecture decisions make it a strong portfolio talking point
• Can be pitched as a real startup targeting India's growing chronic illness management market
• Unique combination of health, AI, and caregiver features not found in a single existing app
