Beware of uneducated reviews
This app is designed for those who DJ. Most of the people that are reviewing it do not. They dont understand what the app is meant for. You are supposed to play a song in your iTunes and then open this app. You then use the pitch slider (someone referred to it as being upside down but it is actually accurate to its orientation on a real turntable) to adjust the tempo of the loop to put it in time with the song playing. Think of it as a live mash-up. This is what a DJ does when they play out. Therefore do not necissarily listen to uneducated reviewers. Though it is limited, its function is far more purposeful then an uneducated person might see.
