Ratings and Reviews

Pretty useless so far


I purchased this app because it looked like it had the features I need. When I first opened the app, it started playing some annoying music which was irritating since I was in a meeting. I can’t find any way to get it to analyze what is coming in through the microphone! The app has microphone access in the Settings app. I don’t see anywhere else to configure it. The developer’s website won’t open for me, so my only recourse is to leave a review here.

Used to work well, but no more.


This app used to work super well, and I would use it to EQ my PA systems all the time. But lately it just keeps playing some sort of instrumental music and only reads the frequencies of the song, and I cannot find a way to turn it off. The app is officially useless.
