Free RTA App That Can Load Mic Calibration Files?

[DaboTheCat]

Mic: Dayton Audio iMM-6

Gonna run pink noise through my car setup and use the Dayton Audio iMM-6 and an app with C weighting and see the response across 10 bars that match up with my 10 Band Sony XAV Graphic EQ. Then just kind of make light adjustments to the 10 band EQ to get me into the ballpark. Doing a real DSP tune is just too complicated and expensive for me right now.

I need an app for iOS that can load the calibration file for this for free. I know of one paid one, but I figure there must be a free one out there, right?
Will this work okay and any app suggestions?
