I'm gonna say this right now, there are a bit of things I dislike about this app, number one, I dislike doing the surveys for smoola as it can teach children to do survey's for free stuff, which I am not especially fond of, although, I do like that one of the first songs available is Duet by Pedro Silva, I think it's cool that you can make charts, I do dislike that levelling up takes really long sometimes, and the UI is a bit lame, it's a decent game I do suppose, but not that great.
