01 / THE CHALLENGE
The problem worth solving.
Radio makes conversation immediate. Bringing that experience to phones and browsers means coordinating presence, channel membership, and who is allowed to speak—while keeping the interface simple enough to use in the moment.
02 / THE SOLUTION
How it comes together.
A Flutter client connects to an ASP.NET Core backend. SignalR handles real-time coordination and WebRTC carries voice. Public and private channels share a single-speaker push-to-talk lock, giving the application a radio-like interaction model across devices.
