Lofi Air plays lo-fi music with live air traffic control radio mixed in underneath: a steady beat, and the calm chatter of pilots and controllers below it. It's my favorite thing to work to, and nothing I found did it properly.
It started in 2025 as an iOS app. I have since taken the app down, and Lofi Air now runs as self-hosted firmware on a small ESP32 board with a round touch screen. It streams a lo-fi station, mixes in a live airport feed, and shows a globe of airports you can turn to change the tower. The ATC audio comes from LiveATC.net.
