Would be good if it worked – Metal Loops 2 - The best free Guitar and Drums practice app! Review

Can't get it to work on my iPhone 6s Plus. It won't respond to touch. I like the concept and the way it is supposed to work, but it won't respond. It worked on my iPhone 4. Also please make Audiobus compatible.
