Haa tech

A few months ago this app was updated to compensate for the iPhone's microphone not being able to register the 20Hz - 35Hz range. Since that update (including this last update) the app has way over compensated in that area. I would like to use this app and trust it, but as of now, it's too hard to tell whats accurate when there is constantly a curve upward from 35Hz to 20Hz. It's a better app with the mic's natural roll off. Please fix the compensation or return it to how it used to be. PLEASE!
