Experience
Gossip Line | Location-based Chat Application
https://play.google.com/store/apps/details?id=com.sitech.gossiplineBuilt GossipLine, a nearby public chat platform designed to make local conversations faster, simpler, and more authentic. The app places users into a shared real-time chat room based on their current area, allowing them to talk with people physically nearby while keeping the experience lightweight and free from followers, likes, private DMs, or performance-driven feeds.
The product focuses on anonymous-style local interaction, where users are represented by a display name and emoji avatar rather than exposing their real name or email in chat. Location is used only to connect users to the right nearby room, while exact coordinates are not shown to other users.
