Fun fact, there is some radio streaming built into the iPhone (all the Siri stuff too, so HomePods).

I found this out when a DJ on the radio kept yelling “hey siri play… <insert call sign here>”, and the same with OK Google.

I was getting annoyed, because he kept triggering my HomePod, but it didn’t understand what he said as the command. Then one time it worked. The DJ yelled and my HomePod kicked on and started playing the same station.

I assume this harkens back to the Internet radio that iTunes has supported forever.

It's literally one of the main tabs in Apple Music

They pushed Apple Music 1 so hard, and now filled it with so much other nonsense, that I’m betting most people overlook that it also has their local stations. I have to scroll nearly to the bottom to get to the local stations.

"and real-time radio streaming without requiring internet connectivity." is misleading. iPhones don’t have an accessible FM tuner, so there’s no true offline radio here. The project does P2P audio over Bluetooth/Wi-Fi (walkie-talkie style) and streams FM stations over the internet. Cool demo, but not RF radio — the README makes it sound like the phone can receive broadcast FM, which it can’t.
