car audio absolute need
this app combined with the switcheasy thumbtack microphone makes a very, very accurate method of tuning in your car stereo.
when results are compared to an expensive audiocontrol RTA, the margin of diff. is negligible.
i highly recommend this app.
btw, the microphone sold by this company is also excellent, and an even better match then the above mentioned mic.
