Simple to use and does the job. But every time I open it, it asks to be updated. I have it set to automatically update and when I check My Apps, it says everything is up to date. Still I can't get rid of that request. Also, I got this persistent ticking sound that I couldn't trace. When I discovered PA was running and stopped it, the ticking stopped. An in-app option to disable running in the background would help prevent this.

quite useful. I like this app. more features? pay for them! this is free! for me though the sound on and sound off indicators are the wrong way around. when the indicator is displaying sound off, to my way of thinking the sound should really be off! same with the indicators for left and right- the on/off part is the wrong way around. seems to cause me a fair amount of confusion as I am never sure if it is generating a tone or not, or, what I am sending it to doesn't work. thank you.

this app would be perfect for my application if it was not for the loop tick at low frequencies that I'm testing. I can hear it with all waveforms. unfortunately it makes it unusable for me. I absolutely love the way out with presets though so hopefully one day It can be fixed.
