Smart Navigation. Safe Journeys. Confident Steps. That’s Wavely.

Inspiration

We were inspired by the common yet deeply concerning experience shared by many women, feeling unsafe while walking alone, especially at night at an unknown place. Existing navigation tools prioritize speed or distance, but none focus on safety, which is often the top priority for women navigating urban spaces. WAVELLY was born out of the desire to bridge that gap and empower users with smarter, safety-first navigation.

What it does

WAVELLY is a navigation app that helps users, especially women, choose the safest walking routes based on real-time safety data. It calculates a Weighted Safety Score for every possible optimal path using parameters like historic crime reports, live foot traffic, street lighting conditions, nearby institutions (schools, fire stations, police stations, hospitals, etc.), and user-reported incidents. It also features a AI call feature powered by Gemini API to deter potential threats. A community incident reporting system to help others stay informed and alert.

How we built it

We used the Google Maps API for location tracking, route rendering, and real-time navigation. The custom safety scoring system creates a safety score by processing data from our custom databases having details of crime, foot traffic, and contextual sources. The Gemini API powers the AI call system, creating a convincing simulation of talking to a known person in case of emergencies.

Challenges we ran into

Balancing accuracy and sensitivity in the keyword-triggered emergency system. Combining multiple safety parameters into a meaningful, real-time score without overwhelming the user. Simulating realistic fake calls that feel convincing without actual audio from known persons. Ensuring privacy and speed in sharing emergency locations securely.

Accomplishments that we're proud of

Successfully integrating Google Maps with safety overlays and custom scoring. Integrated Gemini API for AI calling feature. Creating a polished user experience that balances function and discretion. Designing a compelling, community-driven concept that aligns with Tech for Good and Women Empowerment.

What we learned

How to leverage navigation APIs beyond traditional use cases. The importance of user psychology in designing safety features. How to merge real-time data, and emergency logic into one cohesive flow. The power of collaborative brainstorming and rapid prototyping in a hackathon setting.

What's next for Wavelly

Integrating custom fake call voices and scripted scenarios. Adding a beeper/SOS vibration system for subtle emergency signaling. Smartwatch and wearable device integration for easier access. A Guardian Mode, where friends can track your journey live. Deploying on app stores and building partnerships with local safety organizations and city data sources.
