Total Failure

I purchased this app because LA Fitness uses an FM Band to receive reception on their LCD large monitors while using their aerobic equipment (treadmill, elliptical, stairmaster, etc.). However, even though this product had a nice interface, the channels associated with the FM tuner witihin the club did not associate with the Xtend Fm Radio. This was a huge disappointment. Hopefully, somebody will create an FM tuner using my iPhone that works. Yes, I know Apple sells an additional device for FM reception which is expensive, but an app should be able to work. Perhaps, there is a tweak that I need to do, but there was none that I found. Please advise with a reply, if there is one.
