Works pretty well. Instructions could be more clear.

Binaural Frequencies

Bought this app awhile ago but never really used it too much. But recently began using it as a binaural beat generator and it's excellent. Only wish that it would continue to run in the background. It stops playing when app is minimized.

Much Better Effort, Great Changes

This is a great effort for a general purpose function generator. A lot of nice ideas were put into it.

The newest release is much more stable and easy to use.
