PS: I hope you'll let us know more about how this works for you in combination with Key Sound™ practice.

The link you provided gives a great 2 minute demo of the app.

I urge everyone reading this to check out the link that anerosmith provided to the demo of the app.

I think it might have great potential in combination with Key Sound™ practice.

Intuitively, I would suggest exploring using the tones for some of the practice sessions, while doing others that are just the Multiple Orgasm Trigger Protocol™ by itself.

I have found over the years that periodically coming back to that baseline Protocol often opens yet new gateways... more or less harvesting what was planted when practiced in combination with some other activity such as these lovely toning bowls.

I also want to say that an app like this is a GREAT OPPORTUNITY since purchasing a set of the bowls is no small investment!
