Works perfectly

I used my phone’s microphone and this app seems to measure frequencies very accurately. I used it to EQ my desktop speakers.

Matches our calibrated microphones.

I work in a Modal lab. I downloaded this app just for quick measurements on the fly, to verify my test setups. Works great. The FFT matches our $90,000 analyzes and calibrated microphones. I am impressed to say the least. Please update allowing for triggers.

Horizontal orientation...

... Only one layout. Can’t flip it over. 😒
