Best Violin app Ive seen

Im not a violinist, but Id like to be... And I do understand how to play a violin. So with all the violin apps I looked at (within reasonable price) this was definitely the best. Although, I would want an option to turn the vibrate off, becuase its not only annoying but eats up the battery. I also have problems getting to bow the right tone, but as I said not a violinist.
