MindWave iPhone app

Anyone tried MindWave for the iPhone [App Store link]?

I've downloaded it and checked out the tracks very briefly, but haven't done any serious testing. The audible side isn't nearly as nice as the bells and rain of Holosync, and one or two of the tracks are a little jarring (the “Sleep induction” track surprised me the most in that regard), but it could be nice for short meditations or other specific purposes.

And it's an iPhone app, so that gives it a few coolness points right there! ;)

I'll report back once I've had a chance to do more testing.

Cheers,
