No idea how to use this app

There are no instructions in how to save, load and play any sing you make up. Contrary to what the description says it is not easy to use as I absolutely do not understand what Im supposed to do. I wanted to hear what I saved and all I got was this annoying loud tapping sound. On top of all this I went to the game developer website and tried to send a comment and question through their online contact option and as much as Ive refreshed it still will not submit my feedback. Im about ready to delete this app.
