Well I've used this for an hour because that's as long as the demo lasts. And that is the first bad point.

The second is the price, it just isn't worth 20 bucks. For that price I can get a couple of those relaxation CDs or some babbling brook mp3s and those I can put in my car as well.

Don't get me wrong this IS a good idea and much needed by a lot of people. I just don't think the pricing is realistic when there are other alternatives available. There's nothing in this app that you couldn't cook up in GarageBand yourself.

If this was under 10 dollars it might be more realistic.
