Sorry if this has already been asked, but I am a little confused as to the two different Android PianoCompanions available, one just PComp and the other PComp Pro. I installed PComp then whilst using it decided to upgrade and pay for this great little app. I then discovered Songtive needed installing which I did but now I discovered that the PComp Pro isn't installed and requires additional payment if I install that. I am just confused as to which one I should have on my Android phone/tablet? Are they one and the same, am I missing out having one installed (PComp) and not the Pro app, which I thought I had upgraded to anyway? (GooglePlay states I haven't got Pro installed and I need to buy it - again?) Before I pay out again I just wanted to know if I need to or not, that's ultimately my question I suppose and how Songtive fits in as I want to make sure I link everything together correctly.
