Apps are at the mercy of the phone hardware and whether the phone OS reports accurately on the hardware's properties. Unless it has a facility for calibration, basically an app can't be used for audio measurement.
Particularly with phone microphones you are at the mercy of the noise-cancellation tech built into the phone which is designed - some phones are really aggressive at mucking up the signal like this. From what I recall not all phones allow this to be turned off, even though the API has a call to do this.
