Was amazing, now absolutely useless

Im a professional sound technician who tunes cinema sound systems. This app saved me carrying an RTA and SPL meter and it was amazing.

Thats no more, now they constantly update the app with very expensive in app purchases and new calibrations. The updates wipe your calibrations and replace them with settings that wont work, unless you buy their EXTREMELY EXPENSIVE mic. The SPL in particular needs to be set with another meter after EVERY UPDATE!!!!!!

Picture this, you fly to a remote location, start testing sound and notice the readings are way off. Then you notice there was an automatic update that reset your calibration and your meter is now wrong. Its not just SPL, the RTA curve shows bass levels 12db high at 30hz. Try setting up a dozen sub woofers in cinemas with no way to measure the output.

I was a huge fan of this app and company but now I have to tell you, save your money! There are other sound apps out there, they are so much cheaper and wont leave you hanging.
