I installed this app as it was recommended to me by my music teacher. Little did I know the Android version doesn't work AT ALL. I can't even use the most basic functionality like restarting from a specific place of my choosing or looping a part. I thus wanted to transfer the app to my iPad where it is supposed to work but it seems I can't do this without paying for it again. I tried contacting the company or the people that made the app but there was absolutely no reaction at all.
