What's New in SonicSwarm
6.0
September 8, 2026
Added iTunes Library import — you can now pick songs straight from your Music app library, not just files or Spotify. Added Bluetooth support — if Wi-Fi is off, the app now works over Bluetooth instead, and shows a little banner telling you when that's happening. Added a Radio feature — a separate, single-phone feature where you type a frequency or station name and it plays that internet radio station. Also fixed a bug where it wasn't finding stations reliably.
