Looking for an Accessible sound analyzer

I am very interested in using room equalization to correct problems in my listening area. There are some very elaborate programs in windows, but I find them extremely difficult to use. I was wondering if anybody knows of an iOS app that works with the iPhone microphone to give a decent reading of the rooms frequency response and reverberation times. Ideally, I'd like to get values that I can plug into a parametric equalizer. I've tried a couple of apps, but I haven't had success with them yet.
