Show HN: Convosphere – Real-life proximity chat (convosphere.app)

3 points by jothetaha ↗ HN
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.

You can try Convosphere at the following links:

This is a great idea! You should try using the app on Firefox mobile iOS, it has a lot of issues. I am using it on desktop in the meantime.

I love the idea, was waiting for ~20 years to materialize. The UI on Android/Web is very inaccessible. Tiniest fonts I ever seen on my screen. Also, on the radius selection widget, the counter showing "1 online" is confusing: I believe the counter should not count myself.

You’re absolutely right about the font — it’s way too small. I already had in mind to enlarge it in the next update. As for accessibility, on Android/Web I’m aware it’s not great: the app currently relies on a specific renderer that only works properly with newer browsers, while on older ones it doesn’t behave as expected. Thanks a lot for pointing it out!
