Show HN: Convosphere – Real-life proximity chat (opens in new tab)

The idea for Convosphere came to me a few years ago, when I was visiting a friend in Sardinia. I had just landed at the airport and needed to get to the train station. I wanted to share a taxi with someone else but didn’t feel like going around asking people one by one. That’s when it struck me: what if there were an app that allowed me to instantly connect with everyone nearby – like a group chat for people in the same location? That became the seed of the project.

On the technical side, Convosphere is built with Flutter for cross-platform development, and the backend currently runs on Firebase+Firestore. The app is available as a web app, Android, and iOS, and it supports location-based group and one-to-one chat, events, and a trust score system for safer interactions.
