I read sheet music, but I also pick up tunes by hearing, I thought I had good ears so I thought this training would be easy. Well, I was wrong, Im not that great at hearing...But that is exactly the point, to get you to find out where you are in need of improvement. In that respect it is doing its job well.
The interface is nice and simple and the lessons a separated by difficulty so it lets you get ready for the next level. All in all a very interesting app and I hope my ears get better with it.
