    I was so excited when I saw that you made background playback supported but I really only want it for the white and pink noise gens. I paid for this just because I play with it so much. Would totally put 5 stars after that's implemented.

    Love this app it's addicting! But when you move the slider it plays the sound for about 3 seconds and at the same time you move it, interfears with the other sound. Overall awesome app love using this in class. :)

    Do you think you could introduce a feature to allow the sweep to stop at multiple designated frequencies? I need to test varying frequency arrangements through extended meditation. The only thing this app is missing for that is an 8 point sweep, for my intended purposes. Please consider, this is a near perfect app.
