Android app user with an Apple iOS question

[AB5ID]

I have an Android phone and use Scanner Radio by Gordon Edwards to listen to my feed. It's by far the best mobile app I have found for many reasons, including it never gets killed in the background, automatic stream reconnect, meta tags display, etc.

My friend has an iPhone and I want to recommend to him the best mobile app for iOS.
My question is, what is the best mobile app for iPhone users?
