I bought this app because it shows clearly that there is a 4 track recorder in the full version which I bought. It turns out you have to pay another $9.99 to get it plus all sorts of other in-app add-ons. Its misleading and their tech support was no help blaming it on ITunes & when I contacted ITunes, they told me to contact the company who sent me back to iTunes with no resolution yet. A waste of time and money as I dont have an irig and bought it for the 4 track recorder. I feel ripped off and scammed out of my money.
