About SigmaHealth

Inspiration

Singapore's dense urban environment and tropical climate make it particularly vulnerable to health outbreaks like dengue fever, air pollution spikes, and infectious diseases. During the COVID-19 pandemic, we witnessed how quickly health situations can escalate and how crucial early detection and community awareness are for public health.

We were inspired by Singapore's smart nation initiative and the wealth of open health data available from government sources. We realized that by combining real-time official health data with crowdsourced community reporting, we could create an early warning system that empowers citizens to become active participants in public health monitoring.

What it does

SigmaHealth is a comprehensive health monitoring platform that transforms how Singaporeans interact with public health data:

  • Real-time Health Dashboard: Displays live dengue cluster data (web scrapping from NEA website), air quality PSI readings, and general health data across Singapore (live data from countrymeters.info)
  • AI Health Chatbot (SigmaBoy): Provides personalized health guidance and answers health-related questions using OpenAI's GPT technology
  • Community Health Reporting: Enables citizens to report health observations with geolocation, creating a crowdsourced health surveillance network
  • Interactive Health Maps: Visualizes government health data and community reports on an interactive Singapore map
  • Daily Health Quiz: Gamified learning system with leaderboards to encourage health education and awareness
  • User Profiles: Personalized health tracking and multilingual support for Singapore's diverse population

How we built it

Technology Stack

  • Frontend: React Native with Expo for cross-platform mobile development
  • Backend: Firebase Firestore for real-time data storage and authentication
  • AI Integration: OpenAI GPT API for the intelligent health chatbot
  • Maps: React Native Maps with Google Maps integration
  • Data Sources: Singapore government APIs for dengue, PSI, and COVID-19 data, Countrymeters

Architecture

  1. Data Integration: Built pipelines to process real Singapore health datasets from MOH, NEA, and other government sources
  2. Real-time Sync: Implemented Firebase listeners for live updates across all app features
  3. Geospatial Processing: Created location-based health data visualization and community reporting
  4. AI Implementation: Integrated OpenAI API with custom prompts for health-focused conversations
  5. Gamification Engine: Developed quiz system with scoring, leaderboards, and user progression tracking

Challenges we ran into

Data Integration Complexity

Singapore's health data comes from multiple government sources with different formats and update frequencies. We built a unified processing pipeline to normalize and combine dengue clusters, PSI readings, and COVID-19 statistics. But most of them came fro data.gov.sg

Real-time Performance

Ensuring app responsiveness while handling multiple real-time data sources required implementing efficient Firebase listeners with pagination and smart caching strategies.

Firebase Security Rules

Balancing community features with data privacy meant designing complex Firestore security rules that protect user data while enabling public health reporting.

AI Safety and Accuracy

Ensuring our health chatbot provides helpful information without giving medical advice required careful prompt engineering and safety filters.

Cross-platform Map Integration

Building consistent map experiences across iOS and Android with complex overlays and real-time markers required extensive testing and optimization.
