Haven’t tried the iOS versions just yet, but absolutely love this app for the Mac. As a kid, I remember sitting in the car around the top-of-the-hour and waiting for my dad to turn on the radio for the news updates. This is that, but from a wide variety of sources (NPR, BBC, ESPN, etc) and always right there on your desktop. Brilliant idea.
I didn’t realise there was a Mac version (gonna get it!), but iOS version is really great!
