Convosphere is a location-based chat app where you can join local conversations, events, and meet people nearby — all without sharing personal data.

Main features: • GeoChat: join or create chats within a custom radius. • TrustScore: reputation system to keep conversations safe. • Events: discover or host local activities. • AI integration: Sfera AI curates local news and creates events based on them. • Teleport mode: explore chats from any city.

I'd love to hear feedback, especially about improving onboarding and local discovery.
