Sound Level Analyzer Lite

Seems to do what it should easily and quickly.

Does not record sound actively

I tried this out in a very noisy environment and it did not register any sound. There are no instructions or settings that I could find. I assume it does not work with my iphone 5s.

Developer Response ,

There may be a problem accessing the microphone. Please check if you have enabled the microphone input in the iOS settings.

Auto rotate gone, up 4 steps back

Ability to auto rotate gone. To see the screen and point the mic is not possible any longer.

UI looks much worse.
