Inspiration
In a world where safety is still a privilege for many girls and women, we envisioned FearlessHer — a smart safety solution that ensures no one walks alone. With rising incidents of harassment and insecurity in public spaces, we wanted to build a tech-driven tool that transforms fear into confidence, powered by real-time intelligence and the cloud.
What it does
FearlessHer is a mobile-first web app that:
Tracks a user's live location using GPS
Shows nearby safe zones like hospitals and police stations
Detects well-lit vs. dark/dangerous streets (mock data)
Sends instant emergency alerts to a trusted contact with the user's location
Offers panic button access to trigger real-time SOS alerts
It acts as a digital bodyguard — proactive, responsive, and always watching out for you.
How we built it
Frontend: HTML, CSS, JavaScript, Leaflet.js for live location maps
Backend: AWS Lambda, API Gateway for serverless emergency alerting
Data Sources: OpenStreetMap for location tiles, mock data for lighting and crime zones
Deployment: Hosted via GitHub Pages, serverless backend on AWS

Challenges we ran into
Tackling CORS issues while sending data to AWS API Gateway
Designing a clean, mobile-responsive UI that still looks urgent and accessible
Mapping mock data for unsafe zones in a meaningful way
Ensuring geolocation tracking is accurate and reliable across browsers
Accomplishments that we're proud of
Successfully built and deployed a fully serverless safety tracker
Created a working panic button that sends emergency alerts with exact GPS coordinates
Mapped real-time user movement with Leaflet and integrated location intelligence
What we learned
How to build and deploy scalable serverless APIs on AWS
Real-world use cases of leaflet.js, geolocation APIs, and OpenStreetMap
Importance of designing with empathy, especially when working on safety-focused apps
Collaboration between UI/UX, backend, and security is key for user trust
What's next for FearlessHer
Integrate real-time crime data APIs to detect risky zones dynamically
Build a mobile app version with offline tracking
Allow parents or friends to track live movements securely
Add AI-based danger prediction using ML on movement patterns
Translate the app into multiple languages to reach rural and regional users
