Remember radio? One signal, everyone hearing the same song at the same moment. SUB/WAVE is that. No playlist to build, no algorithm studying you. You press play and join whatever's already on the air. A DJ runs the station. It's an AI, but it does what a good DJ does: picks the next track, reads the station ID, checks the weather, says something on the way into the song. It never just cuts between tracks in silence. Start it and you're live. Lock the phone, switch apps, get in the car, and it keeps playing, with controls on the lock screen, your headphones, and CarPlay. POINT IT AT ANY STATION It opens on the public station, but it'll play any SUB/WAVE broadcast. Run your own off your music library and paste the address to tune in. Saved a few? Switch between them whenever you like. WHAT'S IN IT • Now playing, with cover art and a live visualiser • The booth — every pick, station ID, and segment as it goes out • Timeline — scroll back through what's played • Requests — send the DJ a track or a mood, hear it answered on air • Schedule — what's coming up • Themes that recolour the whole app to match the station One stream. No skip. It's radio, not a playlist.
