DOES NOT WORK!! (Correction)

You might as well just look at picture of a violin fretboard. This app doesnt work. Waste of money.

Update: after much frustration I have found that you need to hold the bottom end of screen (near the bridge of violin) to get any sound at all. You then tap the frets to alter the note. Tonal quality is not impressive.
