Dont buy this app, because its a total rip off. It says Free, but its not!!!! You have to pay for each Chapter. I just paid .89€ for the Introduction, which is 1 minute and tells you nothing about GarageBand. Totally useless!!!! :( Im a professional Logic, but dont understand how GarageBand works on an iPad, how to get into the mixer section, etc., so I thought this App would help. Maybe it will, maybe not, but having to pay .89€ for a worthless 1 minute intro is a total rip off and waste of money!!!! :(
