Case Study // Public Product 008
Sound Sphere
A live-radio discovery product built around an audio-reactive 3D globe.
Product thesis
Built for a specific user, with privacy as product strategy.
Sound Sphere lets people discover live radio through a spinning, audio-reactive globe. The public web app is live, while the native iOS release is represented only at the safe public surface level until App Review completes.
Audience
Listeners who want music discovery to feel geographic, ambient, and alive.
Privacy stance
The public product is designed around direct listening and local playback state instead of social profiling.
Public proof
Live public web app with a matching native iOS experience moving through review.
