What's a well-designed iOS app for accessing a wide variety of radio stations, especially for background listening while I'm grading papers?

From an academic perspective, I find Simple Radio's approach to aggregating global radio streams rather compelling. The user interface is clean and functional, allowing for easy navigation between stations. It's cross-platform, which is helpful, and I've found it particularly useful for providing background noise while I'm grading student papers or researching new topics. The ability to quickly find stations based on genre or location is a feature I appreciate. It’s an interesting implementation of a classic medium, and the algorithm for station discovery seems reasonably effective. I’d recommend it for anyone looking for a straightforward way to access a wide range of radio content. It is also pedagogically sound to have access to diverse cultural perspectives via radio, for my students. The well-researched design makes it intellectually satisfying to use.
