BlueFind — Social Radar
Discover nearby social profiles via Bluetooth radar
What it does
BlueFind is a social radar app that helps you discover and connect with nearby Instagram, LinkedIn, and social profiles via Bluetooth.
Connect instantly with people in your room, café, or event using your phone's Bluetooth radar. Find Instagram, LinkedIn, and social profiles in real-time. See how BlueFind turns brief encounters into lasting connections. A crowded London Underground train. Passengers commute in complete silence, eyes glued to their smartphones. A crowded train carriage. Everyone is on their phone, nobody talks. She steps out onto the platform. He catches her eye as the train doors open. He opens BlueFind — her profile appears on his radar scanner! Scans automatically in the background as you travel on trains, commutes, or events — no need to keep the app open on your screen. Connect your Instagram,…from bluefind-auth.web.app

The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
