Out of tune

Sadly this app is not quite in tune. Really noticeable in the G chord between the 4 and 2 strings but its far from the only one.
(Also the sampled sounds have way too much fret snap.)
What would otherwise be a killer instrument with loads of flexibility and very intelligent layout becomes sadly frustrating. Savage Apps I Am Ukelele sounds WAY better but lacks the features. Still waiting for that great Ukelele app. Sigh.
