Deceptive In-App Purchases
Edit: latest update has no presets, they are gone and so are the developers apparently.
This is a cool music app but there is a problem with the in-app purchases. You are presented with a variety of in-app purchases and then the last purchase listed is the "Full Version". The problem is, it is not clear that you can simply buy the full version instead of the other in-app purchases. So, if you buy the first couple of add-ons, then buy the full version, you pay twice as much as if you had just bought the full version from the start. Thus, a 2-star not-cool rating.
