This is Lovely.

A wonderful and realistic app. Im a musician myself so I cant stress the importance of a metronome when working on a new piece, or sight reading; Although it is slightly slow, and begins to slow down more and more, I never use the metronome an entire piece, only for the first minute or so. I love even more the actual terms that relate to the speed at the top left corner. So youre music vocabulary grows, as well your counting capabilities. Its great that you can also change which notes get the beat, and how many beats per measure. This a simple, easy, and a wonderful tool. A must for an musician.
