Developer David O’Neill has introduced LooperSonic – a multi-track audio looper and recorder for iPhone & iPad.

You can use it like a loop pedal to make loops, and then arrange those loops into complete songs with cut, copy, trim, paste, reverse, and undo/redo.

When you change the tempo, the pitch changes along with it, like a record player. You can use this to make a guitar sound like a bass, or to sing out of your range.

Here’s the official video intro:
