This was a fun nifty app. It is quite limited though, as far as what you can do with it. Ive had this app for over four-and-a-years now April 2011) and the last update was in 2012, so theres been really nothing new added to it since it first was released.
However, with the most recent update to iOS 9, none of the sound effects work anymore, so that all but renders this App useless. They also never did an update for iOS 8.
It seems that this app is no longer supported so Id strongly recommend against buying it now.
