I' ve heard of iHeart Radio, but I don't think it has an FM tuner. The reason why is: I use my iphone at the gym to listen to music, but sometimes I want to watch t.v. instead. And at some gyms like mine(24hrfitness), in order to hear the sound from the t.v., you have to tune in to the specific fm radio frequency the gym is using for that t.v.
