Description: A simple looping program, but, as the page for the app says, "This app is super simple on purpose. Simple is magic!" Select from 30 different tone/instrument combinations (that would be one for each of those drops in the screen grab above), and set them to a-looping. The sound is both from 1964 and 2064, hypnotic and charming. It's too bad you can't record your kids' (or your) creations, but it's a beautiful introduction to creating song loops.
