Doesn't work at all – Microphone | VonBruno Review

I don't know how this can be, but the volume cannot be controlled at all, swiping up and down as per instructions doesn't do anything! Nor is there any output in the speakers, which is whole point of the app!! Looks like a total gyp. But maybe it just didn't work on my device: iPhone 6s Plus.
