Yes, the radio.
Some phones, and some old iPods — the clip-on Nano, for example — have real radio receivers built in. They can pick up over-the-air AM and FM waves, and play them, just like you were in a car from the olden days. The iPhone and iPad, though, have never had working radio tuners. But thanks to internet streaming, it doesn’t matter. You can listen to live radio anywhere, using an app.
Today we’ll see one super-simple app that works a lot like an old radio, and another app that I don’t really like, but that does pretty much anything you could want in a radio-streaming app.
