dB Volume

If this worked on iPhone 6 it might be useful. But it doesn't even give any help for what the buttons do

It worked very well on my iPhone 5, but it's not working on my iPhone 6. Perhaps incompatible with the new operating system? I hope it can be adjusted because it was very useful.

I tested this app , I compared it to a real db meter and its so close " + or - 1db " so in reality it's " + or - 2db " because a proper db mater may be out by 1 . So in comparison to other apps its the best , well done to the app maker !

Great program and useful. Just a shame the full version is so exxy cause the spectrum analyser looks like it would be good too Keep up the good work!
