Violin Ringer

For a person plays violin for a long time, this is very valuable, because you can play instantly. In fact i have been thinking about making an app like this. My request will be to make a switch to have zoom-in, because my finger is bigger, and I can hardly get it right, please make it to have a choice to expand the finger distance, for 4th finger I can just play next open string.
I am using iPhone 4. Thank you.
(also consider to quantize left finger notes down to like c c# d, like a piano, at this level, we want to play out a correct tune, nit sliding like horror movie.)

Also agree with number 10 comments, for a violin player, te intuitive direction of tilting, for playing G string, is to actually tilt the whole body to left, look at my salvation violin ringer video you will understan what i mean. which the current version imagine you will keep bow horizontal and just tilt violin to the right to get to G, that is intuitively wrong!
