About Project

Gangle is an Event Management App designed for a new generation.

Instead of endless group chats and lost invites, users can now discover local events on a live map, create their own, and connect with people around them.

Our team brought this idea to life from UI design in Figma to full-stack development in Flutter building a smooth, location-based experience that just works.

The Problem - Gangle App Challenge

The client had a simple but powerful vision:

Why isn't there a map where I can just see what's happening around me right now?

They were frustrated with:

  • Complex event platforms
  • No real-time map integration
  • Poor mobile UI in existing apps
  • Lack of user-to-user event sharing
  • No easy way to create micro-events

Live Event Map Integration

We used Google Maps to show events by location and time. It feels like your city is alive again.
